Found in Tanzania (hence the name) in 1967, it has since become a well known and widely distributed gemstone. It has become so popular that in October of 2002 the American Gem Trade Association (AGTA) announced that tanzanite had joined zircon and turquoise in the traditional list of birthstones for the month of December. Tanzanite is associated with contentment and understanding.

Nearly all tanzanite has been heat treated to generate the beautiful violet-blue color this stone is Known for. When first mined, most stones are a muted green color. The only known source of Tanzanite is a five square mile hilltop at Merelani, ten miles south of the Kilimanjaro International Airport in Tanzania.
