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