Design your piece
Why custom
We don't sell off-the-shelf jewelry. Every piece begins with your idea, your style, your story — then it is drawn, modelled, and made by hand. Nothing sits in a display case waiting for a buyer.
Selected work
Our family has worked in the heart of Bangkok's gem district since 1975 — one of the largest trading hubs for precious stones in the world.
When you place an order, we don't pull from a drawer. We walk the district, inspect stones by hand, and select each one specifically for your design. Nothing is bought in bulk.
Inside the craft
Send a photo, a drawing, or just a few words. We turn it into a detailed 3D model so you can see the piece from every angle before a single gram of metal is cut.
Only once you approve the design do we source the stones and begin the work. Most pieces take three to six weeks.
How it worksThree generations, one promise: fine jewelry made honestly, and made for one person only.
The Sangmanee family · since 1975
Our promise
Every gem is sourced to order — selected for your piece, never pulled from inventory.
Priced on the day's metal rate, your stones, and the craftsmanship. No showroom rent, no wholesaler cut.
Lab-grown stones are chemically identical to mined gems — same fire, same hardness, a fraction of the cost.
Begin
Send us your idea — a sketch, a photo, even just a few words. We'll take it from there.
