Prasiolite Vs Andradite Fracture
Fracture is an important parameter when you compare Prasiolite and Andradite Physical Properties. It is necessary to understand the significance of these properties, before you compare Prasiolite Vs Andradite 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 Prasiolite is Conchoidal, ConchoidalWalter Schumann and Gemstones of the world (2001). Andradite fracture is Conchoidal, Uneven, Conchoidal, Brittle, ConchoidalArthur Thomas and Gemstones (2009).
Prasiolite Vs Andradite Luster
A primary knowledge about Prasiolite vs Andradite 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. Prasiolite exhibits Vitreous luster. Andradite, on other hand, exhibits Adamantine and Resinous luster.
