Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Fluorite is ConchoidalWalter Schumann, Gemstones of the world (2001) More from other references, Subconchoidal and Uneven.

Fluorite Vs Covellite Luster

A primary knowledge about Fluorite 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. Fluorite exhibits Vitreous luster. Covellite, on other hand, exhibits Resinous luster.
