Hackmanite Vs Powellite Fracture

Fracture is an important parameter when you compare Hackmanite and Powellite Physical Properties.

Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Hackmanite is Gemstones (2009), Gemstones (2009), UnevenArthur Thomas and UnevenArthur Thomas.

Hackmanite Vs Powellite Luster

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