Natural Tanzanite

Tanzanite is a rare gem variety of the mineral known as zoisite, which is a mineral in the epidote group. Tanzanite's history began in the early 1960's when it was first identified. The name tanzanite was given to this zoisite variety in 1968 by the New York jeweler Tiffany & Co. in honor of the country where it was discovered in the Merelani Hills near Mount Kilimanjaro.

Today, tanzanite of commercial importance is still found only in the Merelani Hills of Tanzania, and we specialize in real tanzanite that was mined in those Merelani Hills! Right now, we are offering natural raw tanzanite pieces and tanzanite mineral specimens in a variety of sizes and qualities, as well as a selection of naturally terminated gem-grade tanzanite crystals.
