Stock photography, photos: Tanzanite Gemstones - Tanzania Stock photos of The gemstone known as Tanzanite, which is only found in several mining areas near Arusha, Tanzania ˆ East Africa. Millions of years ago, metamorphous slates, gneiss stone and quarzites shaped impressive flat insular mountains on the wide planes near Mount Kilimanjaro. In the core of these unusual rises there are stored these valuable crystals. Spectacular and magnificent is the deep blue of Tanzanite, ranging from ultramarine to a light purplish blue. The most coveted color is a blue, which shows a purplish hue shimmering around it, and is extremely spectacular in sizes above ten carats. Typical for Tanzanite is the appearance of several colors in one and the same stone: depending on the perspective, the stone appears blue, purple, or dun yellow.
