A well-cut tanzanite round is simply a sight to behold in natural light! It seems as though you can see into the stone forever. The only shape that compares, in our opinion, is the trilliant. Great for all applications, the round is an industry-standard offering and are readily available. We generally have a good supply of rounds in the system at all times, so if you see an item which is sold, please contact us so that we can order one in for you at current market prices.
