TJ Gold & Diamond — jewellers in Botany, East Auckland — handcraft custom engagement rings and fine jewellery in-house, in natural and lab-grown diamonds.
Every Houston jeweller confirms the same thing: the round brilliant engagement ring is still the most requested style in the city. Deutsch Fine Jewelry, one of Houston's leading luxury jewellers, notes that while oval diamonds and yellow gold are growing in popularity, round diamond solitaires remain the top request across their Houston consultations. The round brilliant accounts for more than 50% of all engagement ring diamond sales in the United States consistently, and Houston reflects that national preference with particular clarity.
TJ Diamond ships round diamond engagement rings fully insured to Houston, Texas, handcrafted in our Auckland workshop in 18ct gold as standard — not the 14ct gold that most Houston retailers including Whiteflash, Diamond Exchange Houston, and Rice Village Diamonds use at comparable price points. Every stone carries a GIA or IGI certificate. Every diamond is individually assessed before setting.
Marcel Tolkowsky published the mathematical proof for the round brilliant's ideal proportions in 1919. A GIA Excellent cut round brilliant today is verified against those same proportions. Over 100 years of independent scientific confirmation is the reason the round brilliant remains the benchmark against which every other diamond shape is measured — and the reason the GIA cut grade exists only for round brilliants, because the round is the only shape with mathematically defined ideal proportions.
Why the Round Brilliant Leads the Houston Market
The round brilliant's dominance is optical, not cultural. Its 58-facet design was calculated by Tolkowsky to maximise three simultaneous visual qualities: brilliance (the return of white light to the observer's eye), fire (the dispersion of light into spectral colour), and scintillation (the sparkle pattern as the stone or observer moves). No other diamond shape has been mathematically optimised for all three simultaneously with the same precision.
The GIA's formal five-point cut grade scale — Excellent, Very Good, Good, Fair, Poor — applies exclusively to round brilliants because the round is the only shape with precisely defined ideal proportions. All other diamond shapes receive only polish and symmetry grades, not an overall proportional cut quality assessment. For Houston buyers who want objective, certificate-backed quality verification, the round brilliant is the only shape that provides it.
What to Look for in a Round Brilliant Ring in Houston
Cut grade — the most important factor
GIA Excellent or Very Good cut is the minimum TJ Diamond recommends. The cut grade determines how efficiently the diamond returns light to the observer's eye. A GIA Excellent cut confirms the stone's proportions are within Tolkowsky's identified optimal range. Below Very Good, the reduction in brilliance is visible to most observers without gemological training. The cut grade matters more than colour or clarity for the visual appearance of the finished ring — a G colour VS2 GIA Excellent cut round brilliant is visually superior to a D colour VVS1 GIA Good cut stone at the same carat weight.
Hearts and Arrows — when it matters
Hearts and Arrows is a specific sub-category of GIA Excellent cut where the pavilion main facets create perfect 8-fold symmetry, producing a visible hearts pattern when viewed through a special viewer from below. Whiteflash's A CUT ABOVE is a Hearts and Arrows product, and it represents the highest tier of round brilliant cut quality. TJ Diamond assesses Hearts and Arrows round brilliants on request. The visual difference from a standard GIA Excellent cut is detectable under specific observation conditions but is not typically visible in daily wear without a special viewer.
Colour grade and the yellow gold advantage
For platinum or white gold, G colour is the practical minimum. For 18ct yellow gold, H or I colour round brilliants appear as colourless as D or E stones in white metal, because the warm yellow gold absorbs the diamond's own warmth. Selecting H colour instead of F colour in a yellow gold setting saves typically $1,500 to $4,000 USD at the 1 carat level with no visible difference. This colour grade saving strategy is particularly powerful for round brilliant buyers in Houston who choose yellow gold over platinum.
18ct Gold vs 14ct Gold for Houston Round Brilliant Rings
Most Houston jewellers — Whiteflash, Diamond Exchange Houston, Rice Village Diamonds, and the majority of Houston retail stores — use 14ct gold (58% pure) as the standard setting metal for round brilliant rings. TJ Diamond uses 18ct gold (75% pure) as standard at every price point.
18ct yellow gold round brilliant: The most requested TJ Diamond US configuration. Richer, deeper yellow colour. The colour grade advantage allows H or I colour diamonds to appear colourless, providing meaningful budget savings. Never needs replating.
18ct rose gold round brilliant: A contemporary choice. Warm blush tone complements the round brilliant's symmetric sparkle. No replating required.
Platinum round brilliant: The most durable setting for daily wear. Work-hardens rather than eroding. Keeps prongs secure over decades. No replating. 30 to 50% above equivalent 18ct gold. For platinum, G colour is the recommended minimum.
18ct white gold round brilliant: Rhodium-plated to achieve a white surface. Plating wears with daily contact and requires professional replating every 1 to 3 years. For a ring worn every day for decades, TJ Diamond recommends platinum or yellow gold over white gold.
Popular Round Brilliant Configurations for Houston Buyers
Round brilliant solitaire in 18ct yellow gold or platinum: the most classic configuration. Four-prong and six-prong settings available. Six prongs provide additional security and create a crown-like profile that suits the round brilliant's circular outline particularly well.
Round brilliant with halo setting: a ring of round accent diamonds surrounds the centre stone, adding approximately 0.25 to 0.50 carats of perceived size. A 0.80 carat centre in a halo reads comparably to a 1.25 carat solitaire — the most effective size-per-dollar configuration for Houston buyers working within a defined budget.
Round brilliant with pavé band: a round brilliant centre set on a pavé-set diamond band amplifies the overall sparkle while the solitaire character of the centre stone remains the visual focus.
Natural and lab-grown round brilliant diamonds: lab-grown round brilliants carry GIA certification and are graded on the same cut scale as natural stones. A $5,000 USD budget achieves approximately 1.5 to 2.0 carats GIA Excellent cut lab-grown round brilliant at TJ Diamond — compared to approximately 0.7 to 0.9 carats natural at Houston retail pricing at equivalent quality.
The TJ Diamond Virtual Consultation for Houston Round Brilliant Buyers
Even with a GIA certificate providing the proportional cut grade, there are qualities that require visual assessment: fluorescence character under different lighting, the presence or absence of Hearts and Arrows pattern, colour appearance in the intended setting metal, and face-up size impression at different carat weights. Product photography under direct overhead studio lighting consistently makes all of these harder to assess accurately.
TJ Diamond's virtual consultation shows Houston buyers the specific stone under multiple lighting conditions including natural light and direct overhead light, so the colour, cut quality, and size can be assessed as they appear in real daily wear conditions. The GIA report number is provided before any commitment so buyers can independently verify grades on gia.edu before the ring ships.

Frequently Asked Questions
Q1: Where can I buy a round diamond engagement ring in Houston?
Houston has strong local options including Diamond Exchange Houston, Whiteflash, Rice Village Diamonds, Lewis Jewelers, and Deutsch Fine Jewelry. TJ Diamond ships round diamond engagement rings fully insured to Houston, Texas from our Auckland manufacturing studio, with GIA or IGI certification on every diamond and 18ct gold as the standard setting metal. For Houston buyers who want to inspect the specific diamond before committing, TJ Diamond offers a virtual consultation via video call showing the actual ring and certificate before any purchase commitment. Rings start from $999 USD and ship to Houston in 5 to 7 business days after completion.
Q2: What makes a round diamond engagement ring the most popular choice in Houston?
The round brilliant is Houston's most requested engagement ring shape and the most popular globally, consistently accounting for more than 50% of all engagement ring diamond sales. The reasons are optical: the round brilliant's 58-facet design, with 33 crown facets and 25 pavilion facets, was mathematically optimised by Marcel Tolkowsky in 1919 to maximise brilliance, fire, and scintillation simultaneously. The GIA grades round brilliant cut quality on a formal five-point scale from Excellent to Poor, providing objective, certificate-backed quality verification that no other diamond shape offers. The round is also the most universally recognised symbol of a fine engagement ring, which matters to buyers who want a ring that reads clearly as a serious commitment to any observer.
Q3: What GIA cut grade should I choose for a round brilliant diamond in Houston?
TJ Diamond recommends GIA Excellent or Very Good cut as the minimum for any round brilliant diamond. A GIA Excellent cut confirms the stone's proportions are within the range identified by Tolkowsky in 1919 for maximum light return. Below Very Good cut, the difference in brilliance is visible to most observers without gemological training. The cut grade is the most important quality factor for a round brilliant diamond — more important than colour or clarity for the visual appearance of the finished ring. TJ Diamond does not stock round brilliant diamonds below Very Good cut grade.
Q4: What is the difference between a round brilliant and a Hearts and Arrows diamond?
Hearts and Arrows is a specific sub-category of GIA Excellent cut round brilliants where the 8-fold symmetry of the pavilion main facets creates a visible hearts pattern when viewed through a special viewer from below, and an arrows pattern when viewed from above. Whiteflash's A CUT ABOVE is a Hearts and Arrows product. Hearts and Arrows diamonds are the highest tier of round brilliant cut quality, producing the most precise and complete light return pattern. TJ Diamond assesses Hearts and Arrows round brilliants on request. The visual difference from a standard GIA Excellent cut is detectable under specific observation conditions, but is not typically apparent in daily wear to the unaided eye.
Q5: How does TJ Diamond compare to Whiteflash for round diamond rings in Houston?
Whiteflash specialises in ideal-cut Hearts and Arrows round brilliant diamonds, and their A CUT ABOVE line is genuinely premium cut quality. However, Whiteflash uses 14ct gold as the standard setting metal. TJ Diamond uses 18ct gold (75% pure) as standard across all round brilliant settings, a meaningfully higher gold purity than Whiteflash's 14ct default at comparable price points. TJ Diamond also provides both GIA and IGI certified options, natural and lab-grown diamonds, manufacturing-direct pricing without retail markup layers, and a virtual consultation service that shows the actual specific stone in realistic lighting conditions before purchase.
Q6: What colour grade should I choose for a round brilliant in Houston?
The recommended colour grade depends on the setting metal. For a platinum or white gold setting, G colour is the practical minimum for a consistently colourless appearance. For an 18ct yellow gold or rose gold setting, G, H, or I colour round brilliants appear as colourless as D or E colour stones in white metal, because the warm metal absorbs and neutralises the diamond's own warmth. Selecting H colour instead of F colour in a yellow gold setting saves typically $1,500 to $4,000 USD at the 1 carat level with no visible difference in the finished ring. This yellow gold colour grade advantage is one of the most significant budget strategies available to Houston round brilliant buyers.
Q7: What is the face-up size of a 1 carat round brilliant diamond?
A well-cut 1 carat round brilliant diamond measures approximately 6.4mm across its face-up diameter. A 0.8 carat round measures approximately 5.9mm. A 1.2 carat round measures approximately 6.8mm. A 1.5 carat round measures approximately 7.4mm. These measurements assume a GIA Excellent or Very Good cut, where the proportions maximise face-up size relative to carat weight. Poorly cut round brilliants may measure smaller at the same carat weight because excess weight is hidden in the depth. For Houston buyers comparing carat weights, TJ Diamond's virtual consultation shows stones at different sizes alongside reference objects for a concrete sense of how each weight appears on an actual hand.
Q8: How much does a round diamond engagement ring cost in Houston?
Round brilliant engagement rings at TJ Diamond start from $999 USD. A 1 carat GIA Excellent cut round brilliant in G colour, VS2 clarity, 18ct gold solitaire setting at TJ Diamond typically ranges from $4,000 to $9,000 USD depending on specific grades. At equivalent quality, comparable rings at Houston retail jewellers including Whiteflash, Diamond Exchange Houston, and Rice Village Diamonds are typically priced 40 to 80% higher due to retail markup layers. Lab-grown round brilliant diamonds at TJ Diamond are available at 50 to 70% below natural equivalents at the same GIA certified quality grades — a $5,000 USD budget achieves approximately 1.5 to 2.0 carats in GIA Excellent cut lab-grown round brilliant at TJ Diamond.
Learn what a promise ring means, which finger to wear it on, how much promise rings cost in NZ, and how to choose the perfect ring for your relationship.
A promise ring is a ring given as a symbol of a personal commitment — most commonly a serious relationship commitment that is meaningful but does not carry the formal weight of an engagement ring or a marriage proposal.
The promise ring is one of the most misunderstood pieces of jewellery in New Zealand, primarily because it sits between two better-defined categories. An engagement ring has a fixed meaning understood by everyone. A casual gift has no particular meaning. A promise ring sits in the space between: more significant than a gift, more personal than a fashion accessory, but not carrying the formal commitment of an engagement. Understanding what a promise ring is and is not helps both the giver and the recipient know exactly what they are giving and receiving.
What a Promise Ring Means
A promise ring carries whatever meaning the giver and recipient agree it carries. This is what distinguishes it from an engagement ring, whose meaning is fixed, and from most other jewellery, which carries no specific meaning at all.
In most relationships in New Zealand, a promise ring represents one of the following commitments:
A pre-engagement commitment: A serious relationship where both people are committed to each other and see a future together, but are not yet ready to formally engage. The promise ring acknowledges the seriousness of the relationship without creating the social expectation of an imminent wedding.
A long-distance pledge: A physical symbol of commitment given when two people must be apart for an extended period, so the ring serves as a daily reminder of the person and the relationship while separated.
A relationship milestone: A mark of a significant point in a relationship, such as a first anniversary or a moment of declared mutual commitment, that both people want to recognise with something more lasting than a dinner or a trip.
A personal vow: A ring given to oneself or to mark a personal commitment of any kind, including a religious purity pledge, a personal goal, or a meaningful private promise. In this context, the ring has no romantic element at all.
None of these meanings is more correct than the others. The meaning is established between the people involved, and no external definition applies.
A promise ring is honest in a way that engagement rings sometimes cannot be. It says: I am committed to you, in the way and to the degree that I am committed, right now. Not more. Not less. That honesty is often more meaningful than a formal gesture made before either person is ready for it.

Which Finger Does a Promise Ring Go On?
There is no fixed rule for the finger a promise ring is worn on, which is one of the most common questions people search for. The most practical and widely adopted approach in New Zealand is the right hand ring finger, for two reasons: it keeps the left hand ring finger available for a future engagement ring without creating confusion, and wearing a ring on the right hand ring finger has a clear visual meaning in most social contexts — it says 'this ring is meaningful but it is not an engagement ring.'
Other options that many people in NZ choose:
Left hand ring finger, worn before engagement — the ring moves to the right hand when an engagement ring takes its place on the left.
Middle finger of either hand — a neutral choice with no strong social meaning attached, suited to people who do not want the ring to invite questions.
Right hand middle finger or index finger — equally valid and entirely personal.
The most important factor is that the finger feels right to the person wearing the ring, and that both the giver and recipient understand what the ring means regardless of which finger it occupies.
When to Give a Promise Ring
There is no rule about timing. A promise ring is appropriate whenever the commitment it represents feels genuine and the giver wants to mark it with something physical and lasting. Some common moments in NZ relationships:
Before a long separation — one or both people leaving for work, study, or travel overseas.
At a meaningful relationship anniversary — the first, second, or third anniversary, when the relationship has become serious but neither person is ready to propose.
When discussing the future together seriously for the first time — a shared acknowledgment of mutual intent without the formality of an engagement.
As a Valentine's Day or birthday gift that carries more weight than a typical gift.
At any point where both people feel the relationship deserves a physical symbol of their commitment.
A promise ring is not appropriate as a substitute for an engagement ring when one person wants to propose and the other is not ready — this use tends to create rather than resolve misunderstanding about the relationship's direction.
Does a Promise Ring Need a Diamond?
No. A promise ring can be any ring with any design. The most appropriate promise ring is one that suits the recipient's taste and feels like fine jewellery without being mistaken for an engagement ring at scale.
A slim plain 18ct gold band with an engraving on the inside — initials, a date, a short phrase — is among the most timeless promise ring choices.
A simple solitaire with a small diamond or the recipient's birthstone reads as clearly fine jewellery and carries personal meaning through the stone choice.
A stackable ring designed to be worn alone as a promise ring and later alongside an engagement ring is a practical choice if the giver expects an engagement to follow.
A ring with a specific design motif — a knot, an infinity shape, a simple geometric form with personal resonance — is appropriate if that motif carries meaning for the couple.
The metal should match or complement the recipient's other fine jewellery. TJ Diamond handcrafts all rings in 18ct gold as standard — yellow, rose, or white gold — and platinum, giving promise rings the same material quality as any engagement or wedding ring from our Auckland studio.
Promise Ring Styles at TJ Diamond
A plain or engraved 18ct gold band is the most classic promise ring choice. For engraving options, see our wedding bands collection — many wedding band styles work equally well as promise rings, particularly our plain and lightly detailed bands which include free engraving.
For a promise ring with a small diamond or gemstone centre, our engagement ring collection includes solitaire styles at various scales that are appropriate as promise rings as well as engagement rings. The smaller end of our solitaire range works particularly well in this context.
TJ Diamond also creates fully bespoke promise rings to order in our Auckland studio. If you have a specific design in mind, a particular stone or metal combination, or an engraving you want, we work from your brief.

Frequently Asked Questions
Q1: What is a promise ring?
A promise ring is a ring given as a symbol of a personal commitment between two people, without carrying the formal meaning of an engagement ring. The commitment represented can vary: most commonly it symbolises a serious relationship commitment that precedes engagement, a mutual pledge to remain together while circumstances keep two people apart, or a personal vow of any kind that one person chooses to mark with a piece of jewellery. A promise ring does not imply that a marriage proposal is coming, though in many cases one does follow later. It is simply a physical expression of a promise — whatever that promise means to the people involved.
Q2: What is the difference between a promise ring and an engagement ring?
An engagement ring carries a specific and universally understood meaning: a formal commitment to marry. When someone gives an engagement ring and the other person accepts, both people understand that a wedding is intended. A promise ring carries no such fixed meaning. It symbolises whatever commitment the giver and recipient agree it means — which can range from a pre-engagement promise to a simple expression of love and dedication. Promise rings are typically less expensive than engagement rings, are given without a formal proposal, are worn on different fingers (usually the right hand ring finger to distinguish them from an engagement ring), and carry no social expectation of a wedding date or announcement.
Q3: Which finger does a promise ring go on?
There is no fixed rule for which finger a promise ring is worn on. The most common choice in New Zealand is the right hand ring finger, which keeps the left hand ring finger available for a future engagement ring and wedding band without creating confusion about the ring's meaning. Some people wear a promise ring on the left hand ring finger before they are engaged, and move it to the right hand when the engagement ring takes its place. Others wear a promise ring on the middle finger or another finger entirely, particularly if the ring was given as a personal vow rather than a relationship commitment. The finger choice is entirely personal and should feel meaningful to the person wearing it.
Q4: When should you give a promise ring?
A promise ring is appropriate whenever a commitment feels meaningful enough to mark with a physical symbol, and the giver wants to give something more significant than a casual gift but is not ready or does not intend to propose. Common occasions include: a serious relationship that both people are committed to but are not ready to formalise as an engagement, a long-distance relationship where the ring serves as a physical reminder of commitment while apart, an anniversary that feels significant without being a formal proposal milestone, or a personal vow that one person wants to mark for themselves. There is no rule about how long a couple must be together before a promise ring is appropriate.
Q5: Does a promise ring need to have a diamond?
No. A promise ring can be any ring with any design. Many promise rings are plain metal bands, simple solitaire rings with a small gemstone, or rings with symbolic details like birthstones, engravings, or meaningful motifs. The ring does not need to follow any particular design convention because it has no fixed symbolic form the way an engagement ring does. The most important quality of a promise ring is that it holds meaning for the people involved, not that it meets any external standard of design or gemstone quality. That said, a diamond promise ring — particularly a small solitaire or a simple ring with a modest diamond — is entirely appropriate and gives the ring the visual character of fine jewellery while remaining distinct from an engagement ring in scale and occasion.
Q6: How much should a promise ring cost in NZ?
Promise rings in New Zealand range from a few hundred dollars for a simple plain band to several thousand dollars for a ring with a significant diamond or gemstone. Because there is no external expectation for what a promise ring should look like or cost, the budget is entirely personal. Most promise rings are less expensive than engagement rings by design — part of what distinguishes a promise ring from an engagement ring is its scale and the occasion it marks. A promise ring that costs $500 to $2,000 NZD covers a wide range of beautiful, well-crafted rings in 18ct gold. A promise ring at $300 to $500 NZD in a fine metal with a small diamond or gemstone is equally meaningful. TJ Diamond handcrafts engagement and fine jewellery rings from $999 NZD, and the same quality of handcrafting applies to any ring commissioned for a personal commitment.
Q7: Can a promise ring become an engagement ring?
Yes, in some relationships the promise ring is later given additional meaning — or replaced by an engagement ring — when the couple decides to formalise their commitment as an engagement. Some people choose to keep the promise ring and add the engagement ring alongside it. Others replace the promise ring with the engagement ring, retiring the first ring as a meaningful object to keep rather than wear. Some couples design the engagement ring specifically to stack or pair with the existing promise ring. None of these approaches is more correct than the others. What matters is what feels most meaningful to the specific people involved.
Q8: What is a good promise ring design for NZ buyers?
The most popular promise ring styles at TJ Diamond are simple, elegant designs that read as clearly fine jewellery without being mistaken for an engagement ring at a glance. A slim 18ct gold band with a small single diamond, a plain polished or brushed band with an engraving on the inside, a simple solitaire with a gemstone in the recipient's birthstone colour, or a delicate stackable ring that can later be worn alongside an engagement ring are all well-suited. The design should reflect the recipient's taste rather than following any convention, and the metal should match or complement any other fine jewellery they wear regularly. 18ct gold in yellow, rose, or white is the most appropriate metal for a fine jewellery promise ring, and is the standard TJ Diamond uses for all handcrafted rings.
Quick answers: Left hand, ring finger, wedding band closest to the hand with the engagement ring above it. They do not need to match. If they do not sit flush, a contoured wedding band solves this. If the combined width feels tight, each ring needs to be sized slightly looser than it would be worn alone.
Getting engaged answers the question of what ring you are buying. Getting married raises a new set of questions that almost nobody thinks about until they are already in the jeweller's office. Which hand? Which order? Do they have to match? What if there is a gap between them? What if they feel uncomfortable together? This article answers all of it.
Which Hand and Which Finger
In New Zealand and most of the English-speaking world, both the engagement ring and wedding band are worn on the ring finger of the left hand. The tradition comes from the Roman concept of the vena amoris the vein of love, believed to run from the ring finger of the left hand directly to the heart. The anatomy is not accurate, but the tradition it created has persisted across centuries and across cultures that have largely adopted Western wedding customs.
Some countries use the right hand instead Germany, Norway, Russia, Greece, and several South American countries among them. In New Zealand, the left hand is the standard, and the combination of engagement ring and wedding band on the left ring finger is what most people expect and most jewellers design for when creating contoured or fitted wedding bands.
The Order Which Ring Goes on First
The traditional order is the wedding band closest to the hand, with the engagement ring sitting above it. This means the wedding band occupies the innermost position on the finger, closest to the heart in the vena amoris tradition, and the engagement ring sits on top.
At the wedding ceremony itself, the convention is to temporarily move the engagement ring to the right hand or to a different finger before the ceremony begins, so the wedding band can be placed on the bare ring finger first. After the ceremony, the engagement ring is moved back above the wedding band into its everyday position. This is why the order matters at the ceremony so the wedding band ends up in the correct position without having to remove it and put it back on.
The order is a tradition, not a rule. Many couples simply wear the rings in whatever order feels most comfortable or looks best on their specific hand. If you prefer the engagement ring closer to the hand and the wedding band above it, there is nothing wrong with that. The symbolic tradition of the wedding band closest to the heart is meaningful if it matters to you, and entirely optional if it does not.
Do the Two Rings Need to Match?
No. Matching is a personal choice. The most practically important question is whether the two rings sit comfortably next to each other without one damaging the other not whether they match in metal or style.
Matching metals: Both rings in the same metal (18ct yellow gold with 18ct yellow gold, platinum with platinum) create a cohesive visual pair that reads as a set. The simplest and most unified look.
Contrasting metals: Different metals can look intentional and distinctive when the contrast is clear. Yellow gold engagement ring with a platinum wedding band, or a platinum engagement ring with a rose gold wedding band, are both valid combinations that read as deliberate.
Yellow gold with white gold: This combination is the one most likely to read as unintentional mismatch rather than deliberate contrast, because the two metals appear similar but not identical under most lighting. If mixing warm and cool metals, the contrast between yellow gold and platinum is more visually distinct and intentional in appearance.
Rose gold with other metals: Rose gold pairs naturally with both yellow gold (both warm metals with subtle tone difference) and platinum (warm against cool, clear and deliberate contrast). Rose gold with white gold carries the same partial-match problem as yellow gold with white gold.
The Most Common Problem When Rings Do Not Sit Flush
The most frequently asked practical question about wearing rings together is what to do when there is a visible gap between the engagement ring and the wedding band. This almost always occurs when the engagement ring has a protruding centre stone or a raised setting that prevents a straight wedding band from sitting flush against it.
A plain straight wedding band placed next to an engagement ring with a significant diamond solitaire will not sit against the ring it will float beside it with a gap where the setting prevents contact. This gap is not a problem with either ring individually. It is the result of combining a straight band with a ring design that extends above the plane of the band.
Three solutions for the ring gap problem
Contoured or shaped wedding band: A contoured wedding band is curved or indented to fit around the specific profile of an engagement ring setting. It sits flush with no gap because it follows the engagement ring's outline. TJ Diamond crafts contoured wedding bands to complement any engagement ring, including rings made elsewhere. Bring your engagement ring to our Auckland studio for a precise fitting.
Wear the rings on separate hands: Some people choose to wear the wedding band on the left hand and the engagement ring on the right hand after the ceremony. Both rings are present and worn daily, but on separate hands, which eliminates the gap problem entirely and gives each ring its own presence.
Wear the engagement ring less frequently: Some wearers reserve the engagement ring for occasions and wear the wedding band alone for daily activities. This also protects the engagement ring from the wear and tear of everyday tasks.
For the full range of TJ Diamond wedding bands including straight and contoured options, see our wedding bands collection.
Ring Width and Comfort When Wearing Two Rings Together
When two rings are worn on the same finger, each ring needs to fit slightly looser than it would as a standalone piece. Two rings sitting side by side compress against each other and reduce the effective space on the finger. A ring sized correctly for solo wear may feel uncomfortably tight alongside a second ring, particularly in warm weather when fingers naturally expand.
Ring width combination
Typical feel together
Practical note
2mm band plus 2mm band
Very comfortable for most fingers
Delicate and minimal as a pair
2mm band plus 4mm band
Comfortable for most fingers
A visible width difference that reads as intentional
3mm band plus 3mm band
Comfortable, moderate finger coverage
The most balanced combination
4mm band plus 4mm band
Comfortable for wider fingers, may feel crowded on narrower fingers
Try both on together before committing
5mm band plus 4mm band
Covers a significant portion of the finger
Ensure each ring is sized slightly loose before ordering
TJ Diamond recommends trying on the specific combination of both rings together before finalising sizing for the wedding band. Our Auckland studio holds all widths for comparison, and virtual consultations can show the proportional difference between width options before any order is placed.
What to Do at the Wedding Ceremony
The convention is to move the engagement ring to the right hand before the ceremony so the wedding band can be placed on the bare left ring finger first. After the ceremony, the engagement ring is moved back to the left hand above the wedding band.
Some people ask a trusted friend or family member to hold the engagement ring during the ceremony to avoid the distraction of managing rings at the altar. Others place it on the right hand just before the ceremony begins. Either approach works. The important thing is that the wedding band is placed directly on the left ring finger first, so it ends up in the correct position without requiring rearrangement after the ceremony.
For more on the ceremony question specifically, see our article do you wear your engagement ring during the wedding ceremony?.
A Note on Protecting Both Rings
Two rings worn together on the same finger will contact each other constantly during daily wear. Over time, the metal of each ring will abrade the metal of the other. This is most visible when a plain metal band rubs against a diamond-set engagement ring the metal of the band can develop wear marks where the prongs or setting of the engagement ring make contact.
The best way to minimise this wear is a contoured band that fits flush against the engagement ring setting, reducing the contact points. Platinum, the hardest fine jewellery metal, is the most wear-resistant choice for daily contact between rings. 18ct gold, both yellow and rose, wears slightly faster than platinum but develops a patina that many wearers appreciate over decades.
TJ Diamond's lifetime warranty covers professional re-polishing and prong maintenance for both engagement rings and wedding bands for the life of every ring we make keeping both rings in their best condition regardless of how they are worn together.

contact our Auckland team to discuss a contoured wedding band fitted precisely to your engagement ring.
A ring that does not fit is one of the most common situations in fine jewellery. A proposal ring sized from a best guess. A wedding band ordered months before the ceremony when weight or temperature had changed. An inherited ring from a family member with different fingers. A ring worn for decades as a finger naturally changes shape. In all these cases, the question is the same: can this ring be resized, and if so, by how much and with what outcome?
The answer depends on three things: the design of the ring, the metal it is made from, and how many sizes need to change. This article covers all three, including the specific ring types that cannot be resized at all.
How Ring Resizing Works
Sizing down — making a ring smaller
To make a ring smaller, the jeweller marks the amount to be removed, cuts a small section out of the band at the back of the ring, and re-joins the two cut ends using solder or laser welding. The join is then filed, sanded, and polished until it is invisible in the finished ring. Done correctly by an experienced jeweller, a size reduction is not detectable in the finished ring.
Sizing up — making a ring larger
To make a ring larger, the jeweller has two options. For very small increases (half a size to one full size in yellow or rose gold), stretching the band over a mandrel is sometimes possible, gradually increasing the diameter while maintaining the band's uniform thickness. For larger increases, or for any platinum ring, the jeweller cuts the band at the back, inserts a small piece of additional metal in the same alloy, and re-joins and polishes the seam to invisibility. Metal insertion produces a more structurally sound and consistent result than stretching, and is the recommended approach for all but the smallest adjustments.
How Many Sizes Can a Ring Be Safely Resized?
The practical safe range for most ring resizing is one to two sizes in either direction. Within this range, the metal can be adjusted without significantly affecting the band's proportions, prong alignment, or roundness. Beyond two sizes, the structural requirements of the adjustment increase substantially.

Which Rings Can and Cannot Be Resized
Plain gold or platinum solitaire: Can be resized. The simplest resize. No stones near the resize area. Most straightforward outcome.
Four-prong or six-prong solitaire with plain band: Can be resized. The prong setting is at the front of the ring, away from the resize area at the back. Standard resize process with prong inspection after completion.
Pavé band (half pavé): Can usually be resized if the stones are set on the top half of the band only, leaving a plain metal section at the back for the resize. Complex and requires a jeweller experienced with pavé maintenance after adjustment.
Half eternity ring: Can usually be resized. Stones are set on approximately half the band circumference, leaving a plain section at the back. The plain section is used for the resize adjustment.
Full eternity ring: Cannot be resized. Stones run continuously around the entire band. There is no plain section to cut into for a size reduction or add metal to for a size increase without disrupting the stone setting. Accurate sizing before ordering is essential for full eternity rings.
Full pavé band: Cannot be resized. Same principle as full eternity: stones cover the entire band with no plain section available for adjustment without disturbing the setting.
Channel-set band (full circumference): Cannot be conventionally resized. Stones are held between two metal channels running the full circumference. Resizing would require removing and resetting all stones.
Tension setting: Cannot be resized. The tension setting holds the diamond by compressing the band. Any change in band diameter changes the tension and compromises stone security.
The most important ring resizing rule in the NZ market: if you are considering a full eternity ring or a full pavé band, measure your ring size precisely before ordering. These rings cannot be adjusted after the fact. A half eternity ring is always the safer choice if there is any uncertainty about sizing.
For more on eternity rings and the specific sizing considerations for full vs half eternity designs, see our article what is an eternity ring? which covers this in detail.
Resizing Gold vs Platinum Rings
Gold rings
Yellow gold and rose gold rings are the most straightforward to resize. The metal is malleable, responds well to both stretching and metal insertion, and solders cleanly. Most NZ jewellers with standard goldsmithing skills can resize a plain yellow or rose gold ring correctly. White gold rings are also gold at their core (alloyed with palladium or nickel) and resize in the same way, but may require rhodium re-plating after the resize to restore a consistent white surface across the band.
Platinum rings
Platinum resizing requires specialist skills and equipment. Platinum has a significantly higher melting point than gold and behaves differently during the soldering and finishing process. A platinum resize performed by a jeweller unfamiliar with the metal can result in visible porosity at the join, surface discolouration, or a seam that polishes out differently from the surrounding metal. A qualified platinum jeweller achieves a seamless, invisible result.
Platinum also work-hardens with each adjustment, meaning it becomes progressively more difficult to work with the more times it is resized. This makes it important to establish the correct size as accurately as possible before the first resize, and to avoid unnecessary adjustments.
TJ Diamond's Lifetime Warranty and Resizing Policy
TJ Diamond's lifetime warranty covers ring resizing for the life of every ring we make in our Auckland studio. If your ring no longer fits due to natural finger size change over time, pregnancy, or any other reason, we resize it at no charge. The warranty also covers prong inspection and stone checking after any resize, since prong alignment can be affected by the adjustment process.
Full details of what TJ Diamond's lifetime warranty covers are documented.
If you are purchasing a ring and are unsure of your size, TJ Diamond recommends visiting our Auckland studio for a calibrated metal sizing measurement before ordering. Browse our engagement ring collection or our
wedding bands collection to see the full range of ring styles and their resizability considerations.

Frequently Asked Questions
Q1: Can an engagement ring be resized?
Most engagement rings can be resized, but the ease and outcome depend on the ring's design, the metal, and how many sizes need to be changed. A plain gold or platinum solitaire band can typically be resized up or down by one to three sizes without affecting the ring's integrity or appearance. Rings with diamonds or gemstones set around the band (full eternity, pavé, or channel-set bands) are more complex to resize and may require additional stone work to maintain secure settings after adjustment. Full eternity rings, where diamonds run continuously around the entire band, cannot be conventionally resized at all. TJ Diamond's lifetime warranty covers ring resizing for the life of every ring we make.
Q2: How many sizes can a ring be resized?
For a plain gold or platinum band, most jewellers can resize up to two to three sizes up or down without significantly affecting the ring's structural integrity. Beyond two to three sizes, the metal must be significantly stretched or compressed, which can affect the band's proportions, the prong alignment, and the overall roundness of the ring. For very large size changes, making a new ring entirely is often a better outcome than repeatedly stretching or compressing an existing one. The practical safe range for most ring resizing is one to two sizes in either direction, with three sizes possible for plain bands in good condition.
Q3: What types of rings cannot be resized?
Full eternity rings — where diamonds or gemstones are set continuously around the entire circumference of the band — cannot be conventionally resized. There is no plain metal section available to cut into for a size reduction, or to add metal to for a size increase, without disrupting the stone setting. For full eternity rings, accurate sizing before ordering is essential. Half eternity rings, where stones are set on approximately half the band with a plain section on the back, can typically be resized by working with the plain section. Rings with complex structural elements, very thin bands, or settings that run to the extreme edge of the band may also be difficult or impossible to resize without compromise.
Q4: Does resizing a ring damage it?
A correctly performed ring resize by a skilled jeweller should not visibly damage the ring. For sizing down, the jeweller removes a small section of the band and re-joins the ends. For sizing up, the jeweller stretches the band or inserts a small piece of additional metal and re-joins it seamlessly. The join should be invisible in the finished ring, and the metal surface should be re-polished to match. The most common risk in resizing is in rings with stone settings close to the resize area: if a prong or setting is near the join, it may require re-tightening after the resize. TJ Diamond's lifetime warranty covers all resizing work on rings we have made, including any stone checking and prong maintenance after the resize.
Q5: How long does ring resizing take in NZ?
Most ring resizes at a professional jewellery studio in NZ take between 3 and 7 working days for a standard plain band resize. More complex resizes, including rings with stone settings that need maintenance after the resize, or rings requiring significant structural adjustment, may take 1 to 2 weeks. Urgent resizes can sometimes be accommodated faster, but rushing a resize increases the risk of visible seam lines or inadequate stone checking after the adjustment. For TJ Diamond rings, resizing is covered under the lifetime warranty and is carried out in our Auckland studio. Contact us to discuss the timeline for your specific ring.
Q6: Can a platinum ring be resized?
Yes, but platinum resizing requires specialist skills because platinum behaves differently from gold during the resize process. Platinum is denser and has a higher melting point than gold, which means it requires more force to work and more precise temperature control when re-joining the band. A platinum resize performed by a jeweller inexperienced with platinum can result in porosity in the join, visible seam lines, or surface discolouration. An experienced platinum jeweller achieves a seamless result. TJ Diamond's Auckland studio works with platinum regularly and all platinum ring resizing is carried out by our experienced team. Platinum's work-hardening property means resizing becomes harder the more times a platinum ring is adjusted, so it is important to establish the correct size as accurately as possible before the first resize.
Q7: How do I know what ring size to order when buying a new ring?
The most accurate method is to be measured in person at a jewellery studio using calibrated metal sizing rings, which account for band width (wider bands require a slightly larger size than narrower bands at the same finger). Online plastic sizer kits are a reasonable approximation for narrower bands but are less accurate for wider bands. If ordering as a surprise gift, common approaches include: borrowing a ring the recipient already wears on the correct finger and tracing the inner circle, asking a trusted family member who may know, or using the average NZ women's ring size (N, approximately US 6.75) as a starting point. TJ Diamond includes a complimentary resize within the first 12 months for any ring we make, so a slightly incorrect size on delivery is not a significant problem for most ring styles.
Q8: Does TJ Diamond resize rings made by other jewellers?
TJ Diamond's resizing service is primarily for rings handcrafted in our Auckland studio and covered under our lifetime warranty. For rings made elsewhere, we recommend consulting the original jeweller first, as they will have the most knowledge of the specific ring's construction, metal composition, and setting details. If the original jeweller is unavailable, a qualified Auckland jeweller can assess whether resizing is appropriate for your specific ring. Contact TJ Diamond to discuss whether we can assist with your specific ring.
Q9: What is the difference between resizing up and resizing down?
Resizing down (making a ring smaller) involves removing a small section of the band and re-joining the ends. This is generally the more straightforward of the two adjustments, as it reduces the band without adding new material. Resizing up (making a ring larger) involves either stretching the band uniformly around a mandrel, or cutting the band and inserting a small piece of additional metal. For small increases (half a size to one full size), stretching is sometimes possible for gold rings. For larger increases, metal insertion provides a more structurally sound and consistent result. Platinum rings are almost always resized by metal insertion rather than stretching, due to platinum's resistance to stretching. Both methods, done correctly, should be invisible in the finished ring.
The toi et moi ring is one of the most significant engagement ring trends of the 2020s, but it is far from a new idea. The style has a history that stretches back to 18th-century France, a provenance that makes it one of the most historically meaningful engagement ring forms available, and a contemporary revival that reflects the most important shift in what NZ buyers want from an engagement ring: personal symbolism over conventional sparkle.
The History of the Toi et Moi Ring
The most famous toi et moi ring in history was given by Napoleon Bonaparte to Joséphine de Beauharnais on the occasion of their engagement in 1796. The ring featured two teardrop-shaped stones: a pear-cut sapphire and a pear-cut diamond, set side by side on a simple gold band so both stones faced the wearer simultaneously. The two stones were understood to represent the two people in the relationship — you and me, toi et moi — permanently united on a single band.
The Napoleon and Joséphine ring sold at auction in Paris in 2013 for approximately 949,000 euros, far exceeding its pre-sale estimate, confirming both its historical significance and its continued resonance as a symbol of romantic intent. The original ring is now in a private collection.
Napoleon Bonaparte proposed to Joséphine with a two-stone ring in 1796, more than 100 years before the modern diamond solitaire became the dominant engagement ring style. The toi et moi is not a trend. It is a return to one of the oldest and most explicitly romantic ring designs in the history of fine jewellery.
The toi et moi style was widely adopted during the Victorian and Edwardian eras, when two-stone rings set with complementary or contrasting gemstones were a popular expression of romantic intent. The style fell out of mainstream fashion in the mid-20th century as the round solitaire became dominant, and experienced a significant revival beginning around 2022.
Why the Toi et Moi Returned in 2022
The contemporary toi et moi revival was driven primarily by high-profile celebrity engagements that featured two-stone rings. Several prominent figures chose toi et moi designs in 2021 and 2022, and the resulting media coverage drove a significant increase in search volume and consumer interest for the style globally and in New Zealand.
Beyond the celebrity influence, the toi et moi revival reflects a broader shift in what engagement ring buyers in NZ want from their rings. The two-stone design offers something the conventional solitaire cannot: a ring that is visually and symbolically specific to two people, where the choice of each stone and the relationship between the two stones communicates something about the relationship itself. For couples who shop for the ring together — which a growing proportion of NZ buyers do — the toi et moi allows both people's aesthetic preferences to be represented in a single ring.
The Most Popular Toi et Moi Combinations
The toi et moi's defining characteristic is that both stones face the wearer simultaneously, so their visual relationship — the contrast or complement between them — is always visible. The most popular combinations in the current NZ market reflect different approaches to that relationship.
Stone combination

Brilliance alongside colour — endless personal options
The most personally specific option. Birthstone, favourite colour, meaning.
How to Wear a Toi et Moi Ring
A toi et moi ring is most commonly worn as an engagement ring on the ring finger of the left hand. The two stones typically sit side by side across the width of the finger rather than stacked vertically, giving the ring a horizontal orientation that reads differently from a conventional single-stone ring.
Wide fingers: The horizontal two-stone orientation suits wide fingers particularly well, drawing the eye across the finger and creating width rather than length.
Narrower fingers: Choose two elongated shapes pointing in the same direction (oval and pear with both tips toward the nails, or two ovals tilted inward toward each other). The directional composition elongates the visual line of the finger.
Wedding band pairing: A plain slim band in the same metal typically sits most comfortably alongside a toi et moi ring, as the two-stone profile can be complex to fit a contoured band against. A plain band on each side of the toi et moi also creates a striking stacked composition.
Toi et Moi vs Three-Stone Ring
The toi et moi and the three-stone ring are both multi-stone engagement ring styles, but they represent different design philosophies.
Toi et moi (two stones): Two stones of similar or complementary visual weight, set as equals. No hierarchy. The symbolic meaning is two people of equal significance, represented side by side. The viewer's eye moves between the two stones.
Three-stone ring: One dominant centre stone flanked by two smaller side stones. Clear hierarchy. The traditional symbolic meaning is past, present, and future. The viewer's eye is directed to the centre stone first, with the side stones as supporting elements.
For the three-stone style, see our three-stone engagement rings collection.
Designing a Toi et Moi Ring at TJ Diamond
TJ Diamond creates bespoke toi et moi rings to order in our Auckland studio. The design process begins with choosing the two stone types, shapes, and carat weights, then selecting the setting style and band design that places both stones in the correct relationship to each other on the hand.
The most common starting point for NZ toi et moi buyers is the oval and pear combination. See our oval diamond rings and
pear engagement rings for stone shape references.
Browse our full engagement ring collection to see single-stone styles that can inform the aesthetic direction for a bespoke two-stone design.
Both natural and lab-grown diamonds are available for either or both stones in a toi et moi. Pairing a natural diamond with a lab-grown diamond of complementary shape is an increasingly popular choice — the two stones are visually indistinguishable in the finished ring, and the saving on the lab-grown stone can be redirected to a larger natural stone or a more elaborate setting.
TJ Diamond recommends beginning a toi et moi consultation at least 10-12 weeks before your intended proposal date, as sourcing two specific complementary stones takes additional time compared to a single-stone ring.
Contact our Auckland team to arrange a virtual consultation. We can show you the specific stones together before any commitment is made, so you see how the combination reads as a pair rather than assessing each stone individually from photographs.
Frequently Asked Questions
Q1: What is a toi et moi ring?
A toi et moi ring is a two-stone ring featuring two different gemstones or diamonds set side by side on a single band. The name comes from the French phrase meaning "you and me," and the two stones are understood to represent two people in a relationship. The style is one of the oldest engagement ring forms in fine jewellery history — Napoleon Bonaparte gave Joséphine de Beauharnais a toi et moi ring in 1796, set with a pear-shaped sapphire and a pear-shaped diamond. Contemporary toi et moi rings most commonly feature two different diamond shapes, two different coloured gemstones, or a combination of a diamond and a coloured gemstone, set so both stones face the wearer simultaneously.
Q2: Why are toi et moi rings so popular in 2025?
The toi et moi ring experienced a major revival starting in 2022 when several high-profile celebrity engagements featured two-stone rings, including Ariana Grande and Emily Ratajkowski. This celebrity visibility combined with a broader shift in the engagement ring market toward more personalised, non-traditional designs drove significant search volume and purchase interest in the style. By 2025, the toi et moi has become the fourth most-searched engagement ring style in New Zealand and internationally, behind round solitaire, oval solitaire, and halo. The style particularly appeals to buyers who want a ring with symbolic meaning built directly into its design, buyers who prefer a distinctive aesthetic over conventional single-stone settings, and couples who choose the ring together and want both personalities represented in its stones.
Q3: What are the most popular toi et moi stone combinations in NZ?
The most requested toi et moi combinations at TJ Diamond for NZ buyers are: oval and pear diamonds in the same metal (the two elongated shapes create a flowing, complementary composition), round brilliant and oval in 18ct yellow gold (classic meets contemporary within one setting), oval diamond and oval sapphire (a nod to the original Napoleon and Joséphine ring tradition), pear and marquise (two pointed-end shapes creating a directional, sweeping composition), and two oval diamonds of different sizes tilted toward each other. All combinations are available in natural and lab-grown diamonds, with any coloured gemstone specified to custom order.
Q4: Which hand and finger does a toi et moi ring go on?
A toi et moi ring is most commonly worn on the ring finger of the left hand as an engagement ring, the same as a conventional single-stone ring. It can also be worn as a fashion ring on any finger. The two-stone design typically sits more horizontally across the finger than a single-stone ring, as the two stones are placed side by side along the band width rather than stacked vertically. This horizontal orientation suits wide fingers particularly well, as it draws the eye across the finger rather than elongating it. For buyers with narrower fingers who want elongation, a toi et moi with two elongated shapes (oval and pear, or two marquise stones) creates a directional composition that elongates the visual line of the finger.
Q5: Is a toi et moi ring suitable as an engagement ring?
Yes, absolutely. The toi et moi is one of the oldest engagement ring forms in fine jewellery history, worn as a betrothal ring since at least the 18th century. Napoleon Bonaparte gave Joséphine a toi et moi ring as an engagement gift in 1796. The two-stone design carries a symbolic meaning — two people represented in a single ring — that is arguably more personally expressive than a conventional single-stone solitaire. In the current NZ market, the toi et moi is increasingly chosen by couples who shop for the ring together and want the design to reflect both personalities, by buyers who prefer a distinctive aesthetic, and by those who want a historically rooted style that is simultaneously contemporary in its revival.
Q6: Can I customise the stones in a toi et moi ring at TJ Diamond?
Yes. TJ Diamond creates bespoke toi et moi rings to order in our Auckland studio. You can specify any combination of diamond shapes, coloured gemstones, carat weights, and quality grades for each stone. Common custom requests include: a diamond and a sapphire matching a birthstone or significant colour, two diamonds in complementary shapes at different carat weights, a natural diamond paired with a lab-grown diamond of the same shape, or a toi et moi with specific engraving on the band between the two stones. TJ Diamond recommends beginning a bespoke toi et moi consultation at least 10-12 weeks before your intended proposal date, as sourcing two specific complementary stones takes additional time compared to a single-stone ring.
Q7: What is the difference between a toi et moi ring and a three-stone ring?
A toi et moi ring features two stones set side by side, typically of similar or complementary sizes, with equal visual emphasis on both. A three-stone ring features a larger centre stone flanked by two smaller side stones, with the centre stone as the clear visual focus. The three-stone design traditionally represents the past, present, and future of a relationship. The toi et moi represents two specific people in the relationship — you and me — which is a different symbolic framework. Both are multi-stone ring styles, but the toi et moi has no hierarchy between the stones, while the three-stone setting is always anchored by its centre diamond.
Q8: How much does a toi et moi engagement ring cost in NZ?
Toi et moi rings at TJ Diamond start from $999 NZD for a two-stone design with smaller stones, with pricing scaling based on the carat weight, quality grades, and stone types chosen for both stones. Because a toi et moi ring requires sourcing and setting two specific stones rather than one, the total cost reflects both stone costs combined. Lab-grown diamonds are available for either or both stones at 50-70% below natural equivalents, making larger or higher-quality stone combinations significantly more accessible within a defined budget. Contact TJ Diamond for a personalised quote for any specific toi et moi stone combination and design.
The Asscher cut is one of the most historically significant diamond cuts in the fine jewellery world. Created over 120 years ago, it became the defining diamond shape of the Art Deco period, favoured for the way its geometric precision and reflective depth suited the clean architectural aesthetics of the 1920s and 1930s. Today it is the choice of buyers who want an engagement ring that communicates sophistication, history, and architectural character rather than the sparkle maximisation of a modern brilliant cut.
The History of the Asscher Cut
The Asscher cut was created by Joseph Isaac Asscher of the I.J. Asscher Diamond Company in Amsterdam in 1902. The Asscher family were one of the most significant diamond cutting families in history: in 1907, Joseph Asscher was commissioned to cleave the Cullinan Diamond, the largest gem-quality rough diamond ever found, which was eventually cut into stones that became part of the British Crown Jewels.
The original 1902 Asscher cut has 58 facets, a distinctively high crown, a small table, and large deeply trimmed 45-degree corners that give the finished diamond an almost octagonal outline when viewed from above. These proportions were designed to maximise the hall-of-mirrors effect characteristic of step-cut diamonds, while the square outline distinguished it from the rectangular emerald cut that would come to define a later era of fine jewellery.
The Asscher Diamond Company held a patent on the Asscher cut from its creation in 1902. The patent expired after World War II, during which the company's operations were devastated. In 2001, the Asscher family introduced the Royal Asscher cut — a modified design with 74 facets and enhanced light performance — as a trademarked revival of the family's original creation. Standard Asscher cuts produced by other cutters are based on the original 1902 design without the Royal Asscher modifications.
What Makes the Asscher Cut Look Different
The Asscher cut's visual character is defined by four specific properties that set it apart from every other common diamond shape.
High crown and small table: The Asscher cut has a notably higher crown (the facets above the girdle) and a smaller table (the flat top facet) than most modern diamond cuts. This proportion concentrates the hall-of-mirrors effect in the stone's upper portion, producing more visible concentric rectangular reflections when viewed from directly above.
Deeply trimmed corners: The four corners of the Asscher cut are trimmed at 45 degrees, producing a distinctively octagonal outline when the stone is viewed face-up. The corners are more deeply trimmed than those of the radiant cut and at a sharper angle than the emerald cut's smaller corner trims. This octagonal silhouette is the Asscher cut's most recognisable feature at a glance.
Step-cut facets: Like the emerald cut, the Asscher uses long, flat rectangular step-cut facets arranged in parallel rows rather than the triangular and kite-shaped facets of brilliant cuts. These facets create reflective depth rather than sparkle, producing the characteristic hall-of-mirrors appearance.
Hall-of-mirrors depth: When you look directly into the table of a well-cut Asscher diamond, you see a series of concentric rectangular frames receding inward, like looking into the centre of an infinite corridor of mirrors. This is the defining visual quality of the Asscher cut and what draws buyers who have seen it in person.

Why Clarity Grade Is Critical for the Asscher Cut
The Asscher cut's step-cut facets act as windows into the diamond's interior rather than as mirrors that conceal it. In a round brilliant, the complex facet pattern creates sparkle that effectively masks inclusions. In an Asscher cut, inclusions are significantly more visible at equivalent clarity grades because the open table allows an unobstructed view into the stone.
VS2 clarity in an Asscher cut: May show inclusions visible to the naked eye through the open table. Not recommended as a clarity choice for buyers who want an inclusion-free appearance.
VS1 clarity: The practical minimum for an Asscher cut that presents as inclusion-free to the naked eye in most lighting conditions. TJ Diamond's recommended minimum clarity grade for all Asscher cut diamonds.
VVS2 and VVS1 clarity: The cleanest possible appearance through the Asscher's open table. The concentric hall-of-mirrors reflections are uninterrupted by any visible inclusions. The most technically impressive clarity presentation available in a step-cut diamond.
This clarity requirement is the Asscher cut's primary quality consideration and the most important distinction between the Asscher and a brilliant-cut diamond of the same carat weight and price.
Colour Grade and the Open Table
The Asscher cut's large open table also allows colour to be seen more readily than in brilliant-cut diamonds. For a platinum or white gold setting, F or G colour is the recommended minimum. For an 18ct yellow gold or rose gold setting, H or I colour Asscher cuts appear as colourless as F or G colour stones in white metal, because the warm metal's colour is visible through the open table and absorbs the diamond's own warmth simultaneously. This warm metal colour strategy provides a meaningful budget advantage for Asscher cut buyers in yellow or rose gold.
Ring Settings for Asscher Cut Diamonds in NZ
Asscher cut engagement rings: solitaires, halo, and all engagement ring styles for the Asscher cut. The most classic Asscher setting is a four-prong solitaire placing prongs at the trimmed corners, allowing maximum light entry from all angles.
Browse our full Asscher cut diamond rings range for anniversary, self-purchase, and fashion ring styles alongside engagement options.
Bezel setting: a metal rim encircles the Asscher's perimeter, producing a clean Art Deco-influenced profile that suits the vintage character of the shape particularly well.
Halo setting: a ring of round accent diamonds surrounding the square Asscher creates strong visual contrast between the geometric square outline and the circular halo, while amplifying the perceived centre stone size.
For comparison with the related step-cut rectangular shape, see our emerald cut engagement rings collection.
Asscher Cut Diamonds at TJ Diamond
TJ Diamond handcrafts Asscher cut engagement rings in our Auckland studio in 18ct gold and platinum. Every Asscher cut diamond carries a GIA or IGI certificate. TJ Diamond assesses every Asscher cut individually for clarity presentation through the open table before selection — the same assessment applied to emerald cut diamonds, which share the step-cut clarity visibility challenge.
Natural and lab-grown Asscher cut diamonds are both available. Lab-grown Asscher cuts carry GIA or IGI certification at the same quality grades as natural stones, at 50-70% lower prices. For buyers who want VS1 or VVS clarity, which the Asscher cut demands, lab-grown makes the highest clarity grades significantly more accessible within a defined NZ budget.
Contact our Auckland team to arrange a virtual consultation. We show the specific Asscher cut diamond under multiple lighting conditions so the hall-of-mirrors effect and clarity character are visible before any purchase commitment.
Frequently Asked Questions
Q1: What is an Asscher cut diamond?
An Asscher cut diamond is a square diamond with deeply trimmed corners and parallel step-cut facets arranged in rows on both the crown and pavilion. Created by Joseph Asscher in Amsterdam in 1902, the Asscher cut produces a distinctive hall-of-mirrors effect: concentric rectangular reflections visible through the open square table, creating a depth and architectural clarity that no brilliant-cut diamond replicates. The Asscher cut is the original square step-cut diamond, predating the emerald cut's rectangular step-cut design. Its high crown, small table, and deeply trimmed 45-degree corners give it a more dramatic visual character than any other step-cut shape.
Q2: What is the difference between an Asscher cut and an emerald cut diamond?
Both are step-cut diamonds with parallel rectangular facets, but they differ in outline, proportion, and visual character. The Asscher cut is square (length-to-width ratio as close to 1.00 as possible) with large, deeply trimmed 45-degree corners that create an almost octagonal outline. The emerald cut is rectangular with smaller trimmed corners. The Asscher's higher crown and smaller table produce a more concentrated, dramatic hall-of-mirrors effect in a compact square. The emerald cut's lower crown and larger table produce a wider, more expansive reflective quality. Both require VS1 clarity or better for an inclusion-free appearance, as the step-cut facets reveal inclusions more readily than brilliant-cut diamonds.
Q3: Why does the Asscher cut require higher clarity than round brilliants?
The Asscher cut's step-cut facets act as windows into the diamond's interior rather than mirrors that return light. A round brilliant's complex triangular facet pattern creates a sparkle effect that masks inclusions very effectively — a VS2 round brilliant almost never shows inclusions to the naked eye. An Asscher cut's flat, parallel facets offer no such concealment. Inclusions are significantly more visible at equivalent clarity grades in the open table of a step-cut diamond. VS1 clarity is the practical minimum for an Asscher cut that presents as inclusion-free to the naked eye. VVS2 or VVS1 delivers the clearest possible hall-of-mirrors depth with no visible interruptions.
Q4: What is the difference between the original Asscher cut and the Royal Asscher cut?
The original Asscher cut, created by Joseph Asscher in 1902, has 58 facets and a distinctive high crown with a small table. The Royal Asscher cut was developed in 2001 by the Asscher family to update the original design with enhanced light performance while preserving the vintage character. The Royal Asscher cut has 74 facets (compared to the original's 58), a slightly higher crown, and a modified facet arrangement that increases the brilliance and fire visible through the step-cut facets. The Royal Asscher cut is patented by the Asscher family. Standard modern Asscher cuts are based on the original 1902 design with various modifications that are not patented.
Q5: What colour grade is recommended for an Asscher cut diamond in NZ?
The Asscher cut's open table allows colour to be seen more readily than in brilliant-cut diamonds. For a platinum or white gold setting, F or G colour is the recommended minimum for a consistently colourless appearance. H colour in white metal may show a slight warmth visible in the open step facets under certain lighting. For an 18ct yellow gold or rose gold setting, H or I colour Asscher cuts appear as colourless as F or G colour stones in white metal, because the warm metal absorbs the diamond's own warmth through the open table. The colour grade advantage of warm metals is particularly significant in the Asscher cut, where the large facets allow both colour and setting metal to be seen directly through the stone.
Q6: What is the ideal length-to-width ratio for an Asscher cut diamond?
For an Asscher cut that reads as a true square, a length-to-width ratio of 1.00 to 1.05 is ideal. Ratios above 1.10 begin to read as rectangular, losing the characteristic square Asscher outline. The Asscher cut is distinguished from the emerald cut in part by its square proportions: buyers who want a rectangular step-cut shape should consider the emerald cut, while buyers who want a square step-cut should prioritise an Asscher ratio as close to 1.00 as possible. The large trimmed corners of the Asscher cut also compress the visual outline, making photographs slightly less accurate than in-person assessment for judging the final proportions on the hand.
Q7: How much does an Asscher cut engagement ring cost in NZ?
Asscher cut engagement rings at TJ Diamond start from $999 NZD. The Asscher cut is typically priced similarly to the emerald cut, reflecting the step-cut family's lower demand relative to brilliant cuts. This means Asscher cut diamonds are generally 15-25% less expensive per carat than round brilliants at equivalent quality grades. The clarity premium required for a step-cut diamond (VS1 or better) partially offsets this price advantage. Lab-grown Asscher cut diamonds are available at TJ Diamond with GIA or IGI certification at 50-70% below natural equivalents at the same quality grades, making the higher clarity grades the Asscher cut demands significantly more accessible within a defined NZ budget.
Q8: What ring settings work best for Asscher cut diamonds?
The Asscher cut's square outline and trimmed corners are compatible with a wider range of settings than diamonds with sharp corner points. A four-prong solitaire is the most classic setting, placing prongs at the four trimmed corners to allow maximum light entry. A bezel setting encircles the entire perimeter including the trimmed corners for maximum protection and a sleek, Art Deco-influenced profile. A halo of round accent diamonds creates strong visual contrast between the square Asscher outline and the circular halo, while amplifying the perceived size of the centre stone. Channel-set side stones with baguette or Asscher-cut side diamonds are a cohesive Art Deco composition that suits the vintage character of the shape.
Ordering a custom piece of jewellery can feel mysterious if you’ve only ever bought from a display cabinet. What actually happens after you say, “Yes, let’s make it”? How does a sketch or an idea become a finished ring that you wear every day?
At TJ Gold & Diamond (TJ Diamond), we’re not just a retailer – we’re a direct‑to‑consumer manufacturer. That means your piece is designed, crafted, and finished by our own team, in our own workshop. In this guide, we’ll walk you through our manufacturing process from A to Z, so you know exactly what you’re getting and why you can feel confident in your choice.
Step 1: Your Vision and Consultation
Every custom piece starts with a conversation.
You might come to us with:
A specific design in mind
A handful of inspiration photos
An existing piece you want to remodel
Or just a feeling of what you like and don’t like
Our team will discuss your style, budget, metal preferences, stone shapes and sizes, and any special details (engraving, hidden stones, profiles, etc.). This can happen in person or online, depending on what suits you best.
The goal of this step:Turn your ideas into a clear, shared design direction.
Step 2: Selecting Your Diamonds and Gemstones
Next, we help you choose the right centre stone and any side stones to match your design.
We’ll guide you through:
The 4Cs: cut, colour, clarity, and carat
The right stone size for your budget and finger size
Different shapes (round, oval, pear, emerald cut, and more)
Matching stones for halos, side stones, or bands
Because we work directly with trusted suppliers and manufacture in‑house, we can balance value and beauty, and explain exactly what you’re paying for.
Step 3: Design, CAD, and 3D Modelling
Once your concept and stones are chosen, our designers translate that into a precise design.
This typically includes:
Detailed sketches and/or digital design
CAD (Computer‑Aided Design) modelling to show the ring from multiple angles
Exact measurements for stone settings, band width, and profile height
You’ll be able to review and approve the design, and request adjustments before we move into production. This step ensures we capture every detail correctly before any metal is cast.
Step 4: Creating the Model and Casting
With your design finalised, we create a physical model.
This may involve:
3D printing or wax modelling based on the CAD file
Preparing the model for casting in your chosen metal (e.g. white gold, yellow gold, rose gold, platinum)
Then, using professional casting techniques, we transform the molten metal into the rough form of your piece. This is where your jewellery starts to physically exist – but it’s still only the beginning.
Step 5: Hand Crafting, Filing, and Assembly
After casting, our jewellers:
Cut away any excess metal from the casting process
File and shape the piece to refine every curve and edge
Assemble multi‑part designs (such as halos, multi‑stone settings, or fitted wedding bands)
This is highly skilled work that blends precision and artistry. Small adjustments at this stage make a big difference to comfort, balance, and the final look.
Step 6: Stone Setting
Next, your diamonds or gemstones are carefully set by our professional setters.
Depending on your design, this can include:
Prong / claw settings
Bezel settings
Channel or pavé settings
Halo and side stone arrangements
Each stone is secured individually, with close attention to symmetry, alignment, and light performance. The aim is not just that the stones stay in place, but that they sparkle at their absolute best.
Step 7: Polishing, Finishing, and Detailing
Once the stones are set, your piece moves to finishing.
Our finishing process can include:
Multiple stages of polishing for a high, mirror‑like shine
Brushed, matte, or other custom finishes if requested
Cleaning to remove any polishing compounds
Final detailing and a thorough inspection
This is where your jewellery looks like what you imagined – only better. All the small marks from manufacturing are removed, and the metal and stones come to life.
Step 8: Quality Control and Final Checks
Before we hand your piece over, it passes through strict quality checks.
We verify:
Stone security and setting quality
Metal finish and overall workmanship
Sizing and fit according to your order
Engraving and special details are correct
Only when we’re completely satisfied does your piece leave the workshop.
Step 9: Presentation, Certification, and Delivery
We then prepare your piece for you:
Professional presentation box
Any relevant diamond or gemstone certificates
Care instructions and cleaning recommendations
Warranty or guarantee details
Whether you collect in person or have your piece shipped, we ensure it’s safely packaged and fully documented.
