Custom Fine Jewellery — Manufactured to Your Specifications

Whether you have a single custom piece in mind or are building a jewellery brand from the ground up, Trinity Designer Jewel manufactures to your exact specifications from our Bangkok atelier — in 9kt to 18kt gold with natural diamonds, gemstones, and pearls.

No minimum order quantity. No middlemen. Direct from manufacturer.

What We Create

We manufacture across the full spectrum of fine jewellery — from classic diamond tennis bracelets to complex invisible set gemstone pieces, bespoke bridal sets, and complete private label collections.

Diamond Jewellery
Engagement rings, tennis bracelets, eternity bands, pendant necklaces, stud earrings, and statement pieces. Natural or lab-grown diamonds in round brilliant, pear, marquise, emerald cut, and fancy shapes. VS to VVS clarity, FG to DEF colour — specified to your requirement.

Invisible Set & Pie-Cut Mosaic Diamond Jewellery
Our signature techniques. Invisible setting creates a seamless gemstone surface with no visible metal between stones. Pie-cut mosaic diamonds replicate the face-up appearance of large solitaire diamonds at a fraction of the cost. Both techniques are manufactured in-house by our specialist setters in Bangkok.

Gemstone Jewellery
Natural rubies, sapphires, emeralds, tanzanite, tsavorite, and other precious and semi-precious stones — set in gold with or without diamond accents. Sourced for quality, matched by hand, and set to your design.

Pearl & Diamond Jewellery
Akoya, South Sea, freshwater, and Tahitian pearls in combination with diamonds or as standalone fine jewellery pieces. Ideal for bridal, gifting, and contemporary fine jewellery collections.

Bridal & Wedding Sets
Necklace, earring, ring, and bracelet sets designed and manufactured as coordinated collections. Natural diamond bridal jewellery manufactured to budget, with GIA or IGI certified centre stones available on request.

Private Label Collections
Building a jewellery brand? We manufacture complete collections under your label — from CAD development and sampling through to production and delivery. We have supplied independent jewellery brands across the USA, Europe, Middle East, and Asia. Your designs remain confidential. No portfolio use without permission.

How It Works

1. Share Your Idea
Send us a sketch, reference image, mood board, or simply describe what you have in mind. WhatsApp, email, or our contact form — whichever is easiest for you.

2. Design & Quotation
We review your brief, advise on materials, proportions, and production options, and send a detailed quotation. For complex pieces we can provide CAD renders before production begins.

3. Approval & Production
Once you approve the design and quotation, we begin manufacturing at our Bangkok atelier. Standard production time is 2–3 weeks for most pieces, 4–6 weeks for complex invisible set or multi-stone designs.

4. Delivery Worldwide
Every piece is quality-checked, hallmarked, and shipped fully insured to your door — anywhere in the world. We ship regularly to the USA, UK, Europe, Middle East, Japan, Australia, and Southeast Asia.

Why Bangkok?

Bangkok is one of the world's leading centres for fine jewellery manufacturing — home to master setters, precision casting facilities, and an established supply chain for diamonds, gold, and gemstones.

Manufacturing in Bangkok means:

  • Significantly lower production costs than equivalent work in Europe or the USA — without compromising on quality
  • Direct access to Thailand's established gemstone market — rubies, sapphires, and coloured stones sourced at competitive prices
  • Specialist expertise in technically demanding setting techniques — invisible setting, pavé, channel, and bead setting
  • Faster turnaround than many Western manufacturers with equivalent or superior craftsmanship

Trinity Designer Jewel has been manufacturing fine jewellery in Bangkok for over two decades, supplying retailers, private label brands, and private clients across four continents.

Frequently Asked Questions

Is there a minimum order quantity?
No. We accept single custom pieces and large production runs equally. A private client ordering one bespoke ring receives the same attention as a retailer ordering fifty pieces.

How long does production take?
Standard pieces take 2–3 weeks from order confirmation. Complex designs involving invisible setting, multiple stones, or CAD development take 4–6 weeks. We confirm lead times before you commit to an order.

Can you work from my own design?
Yes. Send us your sketch, CAD file, technical drawing, or reference image and we will work from it. All client designs are treated as confidential — we do not reproduce or share your designs without written permission.

Do the diamonds come with certificates?
GIA and IGI certification is available for natural diamonds above 0.30ct. Lab-grown diamonds above 0.50ct can also be certified on request. We confirm certification options at the quotation stage.

Do you ship to my country?
We ship worldwide via FedEx and UPS with full insurance. We ship regularly to Saudi Arabia, UAE, USA, UK, Czech Republic, Japan, Pakistan, Australia, and across Europe and Southeast Asia.

What are your payment terms?
50% deposit to commence production, balance before shipment. We accept bank transfer in USD, EUR, GBP, and THB.

Can I visit your atelier in Bangkok?
Yes — studio visits are welcome by appointment. Contact us via WhatsApp or email to arrange.
