African Queen. Investment grade. Tanzanite is found in only one spot on earth: Tanzania, East Africa, at the foot of Mount Kilimanjaro. Local herdsmen happened across the first known Tanzanite crystals just a few decades ago, and Tiffany & Company named the gemstone for its location of origin. This exceptionally large, perfect specimen is the radiant blue-violet that defines the stone. An electrifying addition to any collection, and powerful inspiration for a piece of High Jewelry.
