Tanzanite continues to be on the most valuable gemstones on the market today. This due to the scarcity of Tanzanite itself. It is only found in one area of the world making it a very rare gemstone. Tanzanite is only found in Simanjiro District of Manyara Region in Tanzania, in a very small mining area near the Mererani Hills. Tanzanite is like Diamond, but Tanzanite is at least 1000x more valuable and more rare than Diamond.
