Prehnite Vs Chrysocolla Fracture
Fracture is an important parameter when you compare Prehnite and Chrysocolla Physical Properties. It is necessary to understand the significance of these properties, before you compare Prehnite Vs Chrysocolla fracture. Whenever a gemstone chip breaks, it leaves a characteristic line along its breakage. Such lines are known as fracture and are used to identify the gemstones in their initial stages of production when they are in the form of rough minerals. Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Prehnite is Uneven, Yellow, White, UnevenWalter Schumann, Gemstones of the world (2001) More from other references, Brittle and Metallic. Chrysocolla fracture is Sub-Conchoidal, ConchoidalArthur Thomas, Gemstones (2009) and Brittle.
Prehnite Vs Chrysocolla Luster
A primary knowledge about Prehnite vs Chrysocolla 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. Prehnite exhibits Vitreous luster. Chrysocolla, on other hand, exhibits Vitreous and Greasy luster.
