🔮 What is Tanzanite?
Tanzanite is a trade name that was first used by Tiffany and Company for gem-quality specimens of the mineral “Zoisite” with a blue color. Tiffany could have sold the material under the mineralogical name of "blue zoisite," but they thought the name "Tanzanite" would stimulate customer interest and be easier to market.
The name "Tanzanite" was given because the world's only known Tanzanite deposit of commercial importance is in northern Tanzania. The name reflects the gem’s limited geographic origin. The mines are all located in an area of about eight square miles in the Merelani Hills, near the base of Mount Kilimanjaro and the city of Arusha.
Although nearly all of the world’s most popular gemstones have been known and used for hundreds of years. Tanzanite was not discovered in commercial quantities until the 1960s. In the short time since then, it has become the second most popular blue gem after sapphire. It is one of a very small number of gems of any color that have been discovered and brought to strong consumer popularity within the past century. This rapid rise to popularity was accomplished mainly by Tiffany’s promotion and Tanzanite’s beautiful blue color.
