Our sourcing

From the Tsavo region,
to our workshop,
to your hand.

Biidii Gems works directly with Kenyan miners and brokers we've known for years. No import houses, no speculative inventory, no middle markup.

Every stone is cut and finished in our own workshop — so we grade the rough ourselves, decide the cut, and sign off on the finished carat. If it leaves our bench, it's met our standard.

Beyond the loose stone

Setting this stone?
We'll work with your jeweler.

A centerpiece stone deserves a setting chosen for it, not an off-the-shelf mount. Bring your own jeweler, or we'll pair you with one of the ateliers we work with in New York and Nairobi.
