Tanzanites are extremely beautiful, rare and valuable because they are mined in only one place in the world - a small deposit in Tanzania (predictions are that within a few years it will run out). You don't need to be a genius to guess what will happen when they say it's out of stock and there won't be any more (its prices will jump dozens of times). The stones are ideal both for investment and for making extremely beautiful and expensive jewelry. Don't miss your chance to own such a magnificent stone. Type: Tanzanite Weight: 2.62ct.
