Williamsite Vs Uvite Fracture
Fracture is an important parameter when you compare Williamsite and Uvite Physical Properties. It is necessary to understand the significance of these properties, before you compare Williamsite Vs Uvite 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 Williamsite is Conchoidal and Handbook of mineralogy (2001). Uvite fracture is Uneven, Conchoidal and Brittle.
Williamsite Vs Uvite Luster
A primary knowledge about Williamsite vs Uvite 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. Williamsite exhibits Waxy, Silky, Resinous and Greasy luster. Uvite, on other hand, exhibits Vitreous luster.
