"Tanzanite"
Tanzanite is the blue and violet variety of the mineral zoisite, caused by small amounts of vanadium. It has rapidly risen to prominence among jewelers and gem enthusiasts. Exclusive to the Simanjiro District of the Manyara Region in Tanzania, it is found in a very small mining area approximately 7 km long and 2 km wide near the Mererani Hills.
Tanzanite is a relatively recent discovery. Tiffany & Co named this blue-violet variety of zoisite in honor of Tanzania, where it was first unearthed in 1967. Because the crystals exhibit different colors depending on the viewing direction, cutters can fashion gems with a range of colors, from violetish blue to bluish violet, depending on how much weight they wish to retain from the rough.
It's noteworthy that non-blue zoisites should simply be called zoisites.
* Note : Every Tanzanite undergoes heating. While some are partially heated underground and mined with a bit of blue color, they are usually heated again to eliminate any remaining brown. This heating process is standard for tanzanite and doesn't impact its value.
