| Tanzanite is a blue variety of the mineral zoisite (epidote group). The vivid blue to violet gemstone is a testament to man's wizardry in technology. In 1967, miners discovered yellow, green, brown, blue, and pink zoisite crystals in Tanzania, East Africa. Scientists experimenting with some of the crystals discovered that the brown variety changes to blue or violet blue, when subject to heat. Tiffany & Company introduced it to the world bestowing the "tanzanite" name, and the rest is history. Tanzanite is relatively rare and is found only in Tanzania. No one really knows the extent of the supply of rough, but most experts agree that the supply could be exhausted in the near future, unless another source is located. | |||||||||||||||||||||||
