Melanite Vs Proustite Luster

A primary knowledge about Melanite vs Proustite 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. Melanite exhibits Subadamantine and Vitreous luster. Proustite, on other hand, exhibits Adamantine luster.
