Emerald Vs Corundum Luster

A primary knowledge about Emerald vs Corundum 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. Emerald exhibits Vitreous luster. Corundum, on other hand, exhibits Adamantine and Vitreous luster.
