Biotite Vs Demantoid Luster

A primary knowledge about Biotite vs Demantoid luster is useful in apparent identifications of these gemstones. 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. Biotite exhibits Pearly and Vitreous luster. Demantoid, on other hand, exhibits Adamantine luster.
