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.

Each one of our tanzanite jewelry items is set with a genuine tanzanite gemstone that was mined in Tanzania. Here at mineralminers.com, we do not have any lab-created tanzanite gems!
