Tanzanite was first discovered during 1967 and is found only in a relatively small area, approximately five square-miles, near the Kilimanjaro Airport in Tanzania, East Africa. It is one of the newest and most exotically vivid-coloured gemstones.
It belongs to the Ziosite mineral species, which is only found in a small umber of locations including India and Tanzania. It comes in various shades of violet-blue, yellow and sometimes green. The less expensive colours range toward a light-purplish blue-violet.
