Fracture observed in Pearl is Gemstones of the world (2001), Gemstones of the world (2001) and UnevenWalter Schumann.

Pearl Vs Covellite Luster

A primary knowledge about Pearl 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. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Pearl exhibits Pearly luster. Covellite, on other hand, exhibits Resinous luster.
