For Retailers, Brands & Independent Jewellers

Trinity Designer Jewel works directly with jewellery retailers, independent stores, and emerging brands across the USA, Europe, the Middle East, and Asia. If you are looking for a reliable fine jewellery manufacturer in Bangkok with genuine specialist capability — not a catalogue supplier — you are in the right place.

We do not work through agents or intermediaries. Every client relationship is direct, every piece is made in our Bangkok workshop, and every order is treated with the same level of care regardless of size.

What We Offer Trade Partners

Direct Manufacturer Pricing
You buy directly from the manufacturer — no agent fees, no middlemen, no markup layers. Our pricing reflects the actual cost of 18kt gold, natural diamonds, and skilled bench time — nothing more.

No Minimum Order
We do not impose a minimum order quantity. New trade relationships typically begin with a small initial order — this allows both sides to verify quality, communication, and fit before committing to larger production runs. There is no pressure to order more than you need.

Full Custom Manufacturing
Send us a sketch, reference image, or written brief and we will develop it into a finished piece. We handle CAD, casting, setting, finishing, and quality control entirely in-house. Your design stays private — we do not share, copy, or reference client designs with any third party.

OEM & Private Label
We manufacture to your specifications under your brand. Whether you need a single signature piece or an ongoing production line, we accommodate both. All client designs and specifications are treated as strictly confidential.

Consistent Quality Standards
Every piece leaves our workshop in 18kt gold with natural diamonds graded F–G colour, VS–VVS clarity as standard. Lower grades are available on request. GIA and IGI certified stones are available for larger individual diamonds.

Reliable Production Timelines
Standard diamond and gemstone pieces: 2–3 weeks from design approval. Invisible-set work: 4–5 weeks. Complex invisible setting or pie-cut pieces: up to 8 weeks. We communicate clearly at every stage and do not make commitments we cannot keep.

Worldwide Insured Shipping
All orders ship fully insured via FedEx or DHL with complete export documentation. We have experience shipping to all major markets and handle customs paperwork from our end.


Our Specialisations

We are not a general jewellery manufacturer. Our three core techniques require a specific level of precision that most workshops cannot consistently deliver:

Invisible Setting
Calibré-cut stones set into gold rails with zero metal visible from above. Available in natural diamonds, rubies, sapphires, and emeralds. One of the most technically demanding settings in fine jewellery — we have been executing it for over 20 years.

Pie-Cut / Mirage Diamond
Multiple precision-cut diamond segments fitted together to present the face-up appearance of a single large solitaire — at a fraction of the cost. Available in round, emerald, Asscher, and pear face-up formations from 0.50ct to 4ct appearance. Exclusive to manufacturers with the cutting and setting precision to execute it consistently.

Bespoke Gemstone Jewellery
Natural rubies, sapphires, emeralds, and other precious stones sourced and set to client specification. We work with calibré-cut, faceted, and cabochon stones across all jewellery categories.
