Pink Tanzanite (or Pink Zoisite, to give it its scientific name) is the rarest of all Tanzanite. It is very seldom mined or seen and fine pieces are hard to get. The cause of colour in Pink Tanzanite is thought to be trace elements of Manganese as opposed to Vanadium which colours the blue variety of Zoisite.
