Tanzanite first found in 1967 in an area of northern Tanzania in eastern Africa.  In 1968, Tiffany & Co. stepped in to promote this stone and gave it a name as “Tanzanite”. The company began using large, fine-quality tanzanites as affordable and more abailable alternatives to the best blue sapphire.

Most-prized colour is a pure blue similar to fine sapphire’s or an intense violet-blue all its own.

Most tanzanite is heat-treated (600-650°C) to turn it from a browish hue to a more marketable blue.
