I have a beautiful yellow/ gold tanzanite round and breathtaking stone. It does have one small inclusion. But other then that it's completely natural. It's 1.44 carats . Dimensions are 7.05 X 7.10 X 4.58. I think this would make a lovely ring set in a gold finish. Thank you for visiting:)) priced to sell. P.S. This stone looks much better in person. It really sparkles!!
