Buy Tsavorite, Gemstones & Soda Ash from Kenya: A Licensed Supplier Guide
How to buy Kenyan gemstones and industrial minerals legally — permits, valuation, lab reports — and the warning signs of scams.
Read guide →Product 08 · Export from Kenya
Kenya hosts world-famous coloured gemstones — notably tsavorite green garnet, first discovered in Taita Taveta — together with industrial minerals such as soda ash from Lake Magadi, and artisanal and small-scale gold.

Mineral and gemstone exports are tightly regulated in Kenya under the Mining Act 2016. Every shipment requires licensed dealers, valuation by the State Department for Mining, payment of royalties, and an export permit. We only work with licensed miners and dealers, conduct KYC on every buyer, and follow OECD due-diligence guidance for responsible mineral supply chains.
Gemstones are offered as rough and selected cut stones. Industrial minerals are supplied in bulk by sea from Mombasa. Gold is handled only through fully licensed, refinery-ready channels with assay certification and banking-grade documentation.
Typical buyers: Licensed mineral traders, gem cutters, jewellers, refiners, manufacturers and industrial users.
8 types available. Specifications are typical; exact parameters are confirmed per lot on the quotation and certificate of analysis.
Type 1 of 8
Kenya's signature gem from Taita Taveta — vivid green, high brilliance. Rough and calibrated cut stones.
Tsavorite is a vivid green grossular garnet coloured by vanadium and chromium. It was discovered in the Taita Taveta region in the late 1960s and named after Tsavo National Park. Its brilliance and refractive index exceed emerald's, and it is rarely treated. Clean stones above 2 carats are rare and command high prices. We offer rough parcels and calibrated cut stones through licensed dealers.

Market-specific guidance on ports, transit times and import requirements.
No. We only trade gold through licensed channels with export permits, assay certificates, full KYC/AML checks and refinery acceptance. Offers of 'cheap gold' without these documents are a common scam — we never operate that way.
Gemstone and gold samples are priced individually and shipped insured. We issue a pro-forma invoice with the parcel weight, lab report and permits.
