A primary knowledge about Ammolite vs Covellite 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.

Covellite, on other hand, exhibits Resinous luster.
