A new window will open and you'll be able to get yourself a real bargain.Tanzanite is the blue/purple variety of the mineral zoisite (Ca2(Al. OH)Al2(SiO4)3) discovered in the Meralani Hills of northern Tanzania in 1967, near the city of Arusha. It is a popular and valuable gemstone when cut, although its durability is somewhat lacking; its tendency to break precludes appropriate use as a ring stone. Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet, and sage-green depending on crystal orientation. However, most tanzanite is subjected to artificial heat treatment to improve its colour: this significantly subdues its trichroism. Courtesy of Wikipedia
