Ethics & Sustainability

Beautiful jewellery should never come at the cost of people or the planet. At TJ Diamond, we believe luxury and responsibility belong together. As a New Zealand‑based manufacturer, we’re committed to ethical sourcing, transparent practices, and continuous improvement in how we design, make, and deliver every piece.

Our Sourcing Principles

We work closely with trusted suppliers who share our values. Our goals are simple:

• Clear, traceable supply chains wherever possible
• Respect for human rights and fair working conditions
• Responsible environmental practices from mine to workshop

We regularly review our sourcing standards and partners so we can keep improving over time.

Diamonds and Gemstones

We aim to ensure that the stones we use are sourced responsibly and aligned with international best practices.

• We require written assurances from our diamond suppliers that their stones comply with recognised conflict‑free standards.
• We favour suppliers who can provide additional transparency about origin and cutting.
• For coloured gemstones, we prioritise partners who are committed to fair labour and community impact.

If you have particular preferences or questions about origin, we’ll do our best to match you with stones that align with your values and provide clear information upfront.

Precious Metals

Metals are a major part of our sustainability focus.

Where possible, we:

• Use reputable refiners and metal suppliers with strong environmental and compliance records
• Support the use of recycled and responsibly sourced metals where it meets our quality standards
• Continually look for ways to reduce waste in our casting and manufacturing processes

If you’re interested in recycled metal options for your piece, talk to us – we’re happy to discuss what’s suitable for your design.

Our Workshop and Environmental Impact

As a manufacturer, we take our workshop footprint seriously.

We’re working to:

• Minimise material waste through careful planning and refining
• Maintain safe, compliant working conditions for our team
• Invest in modern equipment that improves efficiency and reduces unnecessary waste
• Make thoughtful choices about packaging and shipping

This is ongoing work, and we’re committed to making steady, real‑world improvements rather than vague promises.

People, Community, and Craftsmanship

Behind every piece we make is a team of skilled people.

We believe in:

• Fair and safe working conditions in our New Zealand workshop
• Training, upskilling, and supporting the next generation of jewellers
• Building long‑term relationships with our clients, not one‑off transactions

When you choose TJ Diamond, you’re supporting local craftsmanship and a team that truly cares about its work.

Transparency and Future Goals

Ethics and sustainability are journeys, not destinations. We’re committed to:

• Being honest about what we’re doing now
• Sharing improvements as we make them
• Listening to customer feedback and questions
