This is a very interesting and unusual gemstone that will delight a collector. Hailing from Tanzania, it is very unusual for its inclusions of hematite that are iridescent. This gives it an "oil on water" effect that shows every color of the rainbow. This 3.25 carat stone is an excellent example of the variety.
It measures 9.61 x 9.53 x 4.59mm deep. Because it is not an especially dense stone, you get a lot of size for a given carat weight. This makes a large stone a good value.
This stone would make a great conversation piece on its own or set in a pendant.
