Interesting Fact:
Tanzanite is the Tiffany & Co. trade name for blue zoisite, named after the country of origin, Tanzania. 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. Because of its growing popularity, Tanzanite was designated as a modern birthstone for the month of December in 2002. "Tanzanite is the most beautiful blue stone to be discovered in 2000 years." - Tiffany & Co.
Tanzanite has only one source: the hills of Merelani in northern Tanzania.
