Tanzanite
Tanzanite: A mineral that is a deep blue variety of ziosite and is used as a gemstone
Color: blue to deep blue to purple
The tanzanite is a modern stone, discovered only in 1967 in Tanzania, Africa, hence the name, Tanzanite. The tanzanite stone is relatively rare, as it is found and mined in only one place, the Merelani Hills of Tanzania, not far from from Mt. Kilamanjaro. It is believed that the tanzanite supply will die out in future future decades, unless another vein of it is found elsewhere in the world.
