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.
While also found in blue, tanzanite is most popularly known to occur as purple stones, and is the modern exemplification of purple gemstones. Discovered only in 1967 in Tanzania (hence the name tanzanite), this purple crystal is a variety of zoisite, which is a glassy mineral also found in green and yellow.hile most popular in red, garnet also occurs as purple stones. The purple crystals come from the varieties of garnet called pyrope and spessartine. Blue garnet, the rarest of all garnets, itself turns into a purple stone under an incandescent light.
