Genuine Tanzanite Cluster Ring Size 8! NWT

This is a 7.68 carat narural tanzanite ring made of rhodium treated sterling silver. Size 8. NWT ***Natural, gem-quality tanzanite is expected to be depleted within the next 10 to 12 years, though some estimates suggest it could be longer. Once this happens, tanzanite will become an even rarer, more valuable collectible, as new stones can not be formed and there is only one known deposit in the world, near Mount Kilimanjaro in Tanzania.
