Gemstones from Tanzania
Tanzania is extraordinary among gemstone-producing nations in the sheer variety and quality of material it produces. Most famously, it is the sole source in the world of tanzanite — the remarkable blue-violet zoisite discovered near Mount Kilimanjaro in 1967. Tanzania also produces tsavorite garnet, rhodolite garnet, chrome tourmaline, alexandrite, and ruby from the Winza and Mahenge deposits.
Tanzanian Gem Highlights
- Tanzanite: found only in a tiny area near Arusha; strongly trichroic blue-violet.
- Tsavorite Garnet: vivid pure green; found in the Tsavo region bordering Kenya.
- Mahenge Spinel: exceptional vivid pinks and reds from the Mahenge plateau.
- Chrome Tourmaline: intense chromium-green; found in the Umba Valley.
