We source our rough stones ethically and fairly.
Using our trusted network and no matter the size or quality, we source rough diamonds from around the world. We then send most of them to our partner, Bhagwati Gems for cutting and polishing.
Windiam Israel also contributes to this process by pre-cutting and preparing spotted goods.

Windiam Director / Owner
“If diamonds could talk, they’d have a lot of stories to tell. Not only are they a rare mineral billions of years old, but they are also scattered all over the world, often in the most remote locations. Finding and delivering the quality diamonds you need on time and budget from these challenging environments is what we do best. Our team travels the world to stock Windiam’s inventory with rough stones of all sizes and qualities. And if for some reason we don’t have exactly what you need in-house, we’ll use our extensive global network to find it. When we deliver your diamonds, we could tell you all about how it got from a remote river in South Africa to your door. But none of that matters, what counts is that you got just what you asked for, right on time.”
