A primary knowledge about Tantalite vs Dravite 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. Tantalite exhibits Resinous luster. Dravite, on other hand, exhibits Vitreous luster.
