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

Humite Vs Powellite Luster

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