Tanzanite is a rare blue-violet variety of zoisite found only in the Merelani Hills near Mount Kilimanjaro in Tanzania, making it rarer than diamonds. Formed by extreme heat and vanadium, it is prized for its pleochroism (displaying different colors) and is popular for rings, necklaces, and earrings. Prices vary with high-quality stones often heat-treated to enhance color.
This 5mm square cut stone has been set into an adjustable sterling silver ring with zircon accents. It will best fit sizes 6 - 8
