Diamond production in Tanzania
Tanzania's Williamson Mine at Mwadui — the world's oldest operating diamond mine — is famous for producing rare pink diamonds. The mine's recent renovation by Petra Diamonds and the Tanzanian government has revived production. Artisanal diamond mining also occurs in the Lake Victoria region.
Tanzanian diamonds — whether from large-scale mining operations or licensed artisanal producers — are in active demand from institutional buyers in Antwerp, Dubai, Mumbai, and Singapore. The key is proper export documentation: a Kimberley Process certificate from the Tanzania Minerals Audit Agency, an independent valuation or grading report, and chain of custody records.

How to sell tanzanian diamonds internationally
Selling diamonds from Tanzania to international buyers requires two parallel tracks: export compliance (KP certificate, mineral export permit, independent valuation) and buyer qualification (identifying a funded counterparty who can transact through formal escrow or bonded carrier structures). OnePiece handles the buyer side — we maintain relationships with institutional buyers who are actively acquiring tanzanian diamonds and other African origin material.
WhatsApp us with your parcel description: origin, stone type (rough/polished), approximate carat weight, and your documentation status. We will respond within hours and advise whether your material matches an active buyer mandate.
