We Can Set Your Own Stone — Here's How It Works

Not every stone comes from a supplier. Sometimes you have one already.

It might be a centre diamond you sourced yourself. A gemstone you've been holding onto. A stone from a family piece that deserves a new setting. Or simply a situation where you've found exactly what you want and just need the right manufacturer to build around it.

We work with customer-supplied stones regularly — and we welcome these projects.

What We Can Work With

Over 20 years of manufacturing fine jewellery in Bangkok, we have worked with almost every stone type — natural diamonds, lab-grown diamonds, rubies, sapphires, emeralds, pearls, tourmalines, and synthetic stones where the goal is a setting that makes them shine at their best.

One of the more delicate projects we handled was a grandmother's pearl — sentimental, irreplaceable, and fragile — that a client wanted reset into a modern design without any alteration to the stone itself. We designed the setting entirely around the pearl and delivered exactly what was asked.

If your stone is unusual or technically challenging, speak to us first. In most cases it can be done.

How It Works

• Share the stone details with us — dimensions, type, and any certification
• We design the setting around your stone and you approve before production begins
• We update you throughout via WhatsApp
• The finished piece is inspected before it leaves our workshop

Lead times depend on complexity. We give you an honest timeline upfront — not a date we cannot meet.

One Thing Worth Knowing

If your stone is particularly fragile or high in value, let us know before sending it. We will advise on safe transit and handling so nothing is left to chance.
