Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Powellite is Brittle, Conchoidal, Handbook of mineralogy (2001), Handbook of mineralogy (2001), UnevenAnthony et al and UnevenAnthony et al.

Powellite Vs Jet Luster

A primary knowledge about Powellite vs Jet 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. Powellite exhibits Greasy and Subadamantine luster. Jet, on other hand, exhibits Waxy luster.
