Tanzanite is a brownish color (much like the third trichroic color) when it comes out of the ground. Strong Trichroism with two of the colors, blue and purple, being readily visible to the unaided eye. Tanzanites in the larger sizes (2 carats and higher) are quite rare and can be very expensive. The material turns to its blue/purple color after heating.A good quality tanzanite in the 3-5 carat range can cost upwards of US$1,000.00 per carat. There are not any synthetic tanzanites on the market. But there are many imitations that have been developed in an effort to fool people.![]()
