Tanzanite is a royal purple color. It is very blue, but in a violet type of blue. Kilimanjaro is the only place tanzanite has been found. So, this gem is mined only there.

Tanzanite took its name from the country of Tanzania, where it is mined. It is a zoisite mineral that has become one of the most popular gemstones since its discovery in 1967.

overview

Tiffany & Co. was the company that brought tanzanite to the marketplace back in 1967, so it is a fairly modern discovery. It is the pure blue variety of this zoisite mineral gem that is most prized, but it will change colors depending from which angle you view it. When the gem cutter wants to retain more weight, they’ll include more of the violet blue color from the rough stone when cutting it.
