Tanzanite is the blue/purple variety of the mineral zoisite. (a calcium aluminium hydroxy silicate) It was discovered in the Mererani Hills of Manyara Region in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro.

This is only known source in the world and has been depleted over the years. Naturally-formed tanzanite is extremely rare.
TanzaniteOne Mining Ltd. is a gemstone mining company which exclusively mines the blue gemstone.

TanzaniteOne Mining Ltd is a fully owned subsidiary of the London AIM listed resource company, Richland Resources.( AIM : RLD )
Tanzanite is a relatively new gemstone in the world of gemology and jewelry. Since its discovery, tanzanite has sold for as little as $20 per carat and as much as $1,000 per carat or more, for gem-quality, finely coloured stones.

That price may seem like a bargain in time, as tanzanite is a single-source gemstone and that source is expected to be mined out within the next 20 to 30 years based on the latest mining information.
Tanzanites are typically blue or violet-blue, but they can also be rare greenish and greenish-blue shades. Tanzanite is a highly pleochroic gem, meaning it can appear blue from one angle and violet or violetish-blue from another.

Vanadium is the main coloring agent required to produce the rich blue-violet colors that are so highly prized.
