Custom Jeweler · JTC Bangkok
Same certified stones, same factory, same hands the big brands use. Minus the price of the logo, the mall rent, and the four middlemen between them and you.
Who You're Dealing With
I'm Ansh Gupta, a second-generation jeweler working out of the Jewelry Trade Center on Silom Road, Bangkok — the building where much of the world's jewelry trade actually happens before it reaches a display case with a 6x price tag.
My family has been in this trade since 1990. Today I run the workshop end to end: sourcing certified stones, CAD design, casting, setting and finishing, all in-house. When you message me, you're talking to the person who prices your piece, draws it, and checks it before it ships. Not an account manager.
I make everything from engagement rings to fully iced-out chains, in lab-grown or natural stones, and I'll tell you straight which one your piece actually calls for.
The Markup Autopsy
Tap a piece. This is roughly where your money goes at a branded retailer, versus what the same piece costs made factory-direct at my bench.
Example figures for a typical spec, to show where the money goes. Your exact quote depends on stone, weight and design — and it's itemized, so you'll see every line just like this.
The Custom Engine
Engagement rings, iced-out chains and pendants, colored-stone heirlooms, everyday fine jewelry. Lab-grown or natural. If it can be drawn, it can be made.
Certified stones sourced at trade price, CAD drawn in-house, cast and set on my own bench. No subcontract chain marking the piece up at every hop.
Every quote, render, and quality check goes through me. You get one point of contact from first message to unboxing, and my name is on the result.
The Custom Timeline
You approve at every stage. Nothing gets cast until you've seen it and signed off.
Send references, a sketch, or just an idea on WhatsApp. You get an itemized quote — stone, gold, labor, everything visible.
A deposit starts the work. I draw your piece in 3D and send photoreal renders from every angle. We revise until it's exactly right.
The approved design is grown as a wax model — the physical proof of the piece before any gold is poured.
Cast in your chosen gold, stones set by hand, polished and finished at the bench.
You get a close-up video of the finished piece and the stone certificates. Balance is only due once you approve.
Shipped insured worldwide, or collected in person at JTC Bangkok with a coffee.

FAQ
On most custom pieces, 50–80% below comparable branded retail. The stone, the gold and the labor cost roughly the same everywhere. What you're not paying for is the brand premium, the showroom rent, and the layers of middlemen between the factory and the display case.
Yes. Send the reference photos on WhatsApp. I redraw it in CAD, adapt it to your stone and budget, and you approve the render before anything is made.
