This is a cushion cut Mystic Topaz Gemstone with vivid color, brightness, and clarity as shown in these unedited photos. Mystic topaz is quite a new gem type, first seen around 1998. It is natural colorless (white) topaz that has been coated, giving it a unique rainbow color effect. It is not a gem type on its own, but rather considered an enhanced or treated colorless topaz. Since the treatment is a coating, it is not a permanent enhancement, but its remarkable appearance makes it an interesting gem in its own right. Mystic topaz looks similar to mystic quartz. Mystic topaz can be distinguished from quartz by its hardness (8 on the Mohs scale) and perfect cleavage.
