Tanzanite is a breathtaking blue-violet gemstone discovered in 1967 by a traveler, near the foothills of Tanzania’s Mount Kilimanjaro. This lustrous stone with its distinct, desirable colors, is a thousand times rarer than a diamond because it is found only within a 4-kilometer radius of the few existing active mines. Cape Diamond Exchange offers an incomparable range of Tanzanites, both unset, and set in jewelry. Visit us, or order your stone and get a vibrant piece of Africa. Our Tanzanite stones are certified.
