What we deal in

What Giri holds and what Giri can supply are different things. The stock room leans heavily to sapphire; the sourcing reaches much further. Commercial through exceptional — which end of that range we work at depends entirely on the requirement.

Selected stones

A changing selection. What appears here is a small part of what Giri holds, and a smaller part again of what Giri can source. Prices are quoted on request.

Sourcing

What you see online is
a fraction of what
we can find.

Most of what Giri supplies never appears on a website. It moves between people who have worked together for years.

Give us a specification — stone, size, shape, quality, quantity, timing — and you will get a straight answer on whether it can be met and roughly when. If it cannot, we will say so.

The house

Founded in Bangkok, 2000.
Still family-run.

Giri Corporation Gems Tower · Bangrak, Bangkok
Trading since 2000 · RJC certified member 0000 6076

Three decades in the trade produce two things that cannot be bought: judgement about what a stone is actually worth, and the relationships that let you find it.

The company is still run by the family that started it. That is why the same people answer in year thirty as in year one.
