Tanzanite is the blue/violet variety of the mineral zoisite (a calcium aluminium hydroxyl Sorosilicate) belonging to the epidote group. It was discovered by a Tanzanian Jumanne Mhero Ngoma in the Mererani Hills of Manyara Region in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro.
Tanzanite is blue Zoisite, a calcium aluminum silicate, and forms in prismatic, usually striated crystals, transparent to slightly opaque, and ranges in color from deep ultramarine blue to light violet-blue. The most coveted crystals are a saturated blue with a hint of purple around it.
