Our Story

Welcome to Our Family Workshop.

Suparno Jewelry began over 30 years ago as a family gemstone business, at the height of Thailand's ruby and sapphire trade. The name itself is a small piece of that story — drawn from "Supron," our founder's mother's name, blended with "soprano," a nod to jewelry as a form of personal expression.

Today we take on the full journey — sketching, CAD, casting, setting and finishing — so nothing gets lost in translation between your idea and the object in someone's hand. By keeping every process in-house, we control quality, cost and timing from concept to delivery.

Our Bangkok Showroom
How We Work

From Idea to Reality.

Concept & Sketching

Every masterpiece starts as an idea, hand-sketched alongside your team.

CAD Design

Your sketch becomes a production-ready 3D model, planned before we cast a thing.

Casting, Filing & Polishing

The piece is cast, then filed, polished and plated by hand until the finish is right.

Stone Setting

Diamonds and stones set by hand under magnification, all under one roof.

Quality & Delivery

Multi-point inspection, then your finished collection delivered on time.

In The Workshop

Every Piece, Made By Hand.

Behind every finished piece is a lot of unglamorous, careful work — casting the metal, filing down every rough edge, polishing until it catches the light properly, plating where needed. It's slow, repetitive work, done by the same small team every time.

We work with:

Brass
Silver
Gold, 9K–18K
Platinum
Diamonds
Lab-Grown Diamonds
Precious & Semi-Precious Stones
Enamel
Voice
Our People

The Hands Behind Every Piece.

Most of our craftsmen have been with us for years — the kind of patient, close-up work that goes into a ring or a setting isn't something you rush or replace easily. It's just people who know what they're doing, and care about it.

We try to look after that beyond the workbench too — team outings, celebrations, the odd competition. Nothing fancy, just a team that actually likes working together, which shows up in the work itself.

Work With Our Team
Suparno Jewelry owner
Leadership

Led by Kai.

Suparno Jewelry is run day-to-day by Chayankittipat Yongpeerakul — Kai to everyone who works with him. It's still very much a family business, and he stays close to it: quotes, samples, problems, all pass through him directly, so nothing gets stuck waiting on approvals.

That's really the whole approach — a small team that cares about getting things right, built up over 30 years, one order at a time.
