Tanzanite
Tanzanite is the blue/purple variety of the mineral zoisite which was discovered in the Meralani (Merelani) Hills of Northern Tanzania in 1967, near the city of Arusha.
Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet, and burgundy depending on crystal orientation. It is a remarkably rare gemstone coming exclusively from one small locality in Tanzania.
Tanzanite is now considered to be the most precious and sought after stone in the world. Unsurpassed in its unique beauty, this powerful gemstone is truly one of a kind in every sense.
