Hematite Vs Opal Luster

A primary knowledge about Hematite vs Opal 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. Opal, on other hand, exhibits Pearly and Vitreous luster.
