A primary knowledge about Alexandrite vs Powellite luster is useful in apparent identifications of these gemstones.

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Alexandrite exhibits Vitreous luster. Powellite, on other hand, exhibits Greasy and Subadamantine luster.
