Tanzanite Zoisite is an exquisitely beautiful precious gemstone sourced from the foothills of Mount Kilimanjaro in Tanzania. This is the only source in the world for this unique gemstone, making it rare and desirable. Tanzanite is a mix of blue and purple hues, occasionally green, and has a strong pleochroic effect that makes it sparkle intensely from all angles. Tanzanite Zoisite is a sought-after gem for its beauty and rarity. If you don't see your perfect Tanzanite in our online store, contact Gemma at The Sapphire Merchant today with your requirements.
