Semi Precious Stone Tanzanite



The name tanzanite was a trade name coined by Tiffany & Co. shortly after the gem's were discovered, an obvious allusion to its country of origin. This was thought necessary in order to make the stone remarkable to the public: the name has since stuck as a varietals designation. Tanzanite's present-day popularity as a gemstone is very largely thanks to Tiffany's marketing campaigns. The mining of tanzanite nets the Tanzanian government approximately USD $15 million annually, the finished gems later being sold mostly on the US market for its sales totaling approximately USD $400 million annually.
