Luster is the measure of light that gets reflected when incident on a finished cut gemstone. There are two major types of lusters: Silky and Adamantine. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Simpsonite exhibits Adamantine luster. Sillimanite, on other hand, exhibits Silky, Subadamantine and Vitreous luster.
