New Zealand’s Full-Scope Jewellery Manufacturer
TJ Gold & Diamond operates jewellery manufacturing facilities in Auckland, New Zealand, and Houston, Texas. Our in-house capabilities include CAD design, 3D printing, casting, stone setting, polishing and finishing, giving us control over the entire manufacturing process.
By purchasing directly from the manufacturer, you avoid traditional importers, wholesalers and retail markups while benefiting from greater customisation, consistent quality control and exceptional value.
From engagement rings and wedding bands to earrings, pendants, bracelets and bespoke pieces, every item is carefully manufactured from design through to final inspection.
TJ Gold & Diamond is proud to hold recognised New Zealand certifications and registrations supporting local manufacturing, authenticity, and environmental sustainability:
3. Toitū - Environmental Sustainability
1. Consultation & Design
Every piece starts with an idea.
We discuss your design, budget, preferred metal, and any diamonds or gemstones you'd like included. You can bring photos, sketches, or simply tell us what you're looking for.
2. CAD Design
Once we understand your vision, we create a detailed 3D CAD design.
This allows you to see your jewellery before manufacturing begins and make any changes if needed.
3. Model Creation
A model is produced from the approved design to ensure all proportions and details are correct before production.
