Star Sapphire Vs Williamsite Fracture

Fracture is an important parameter when you compare Star Sapphire and Williamsite Physical Properties. It is necessary to understand the significance of these properties, before you compare Star Sapphire Vs Williamsite 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. Williamsite fracture is Conchoidal, Conchoidal and Handbook of mineralogy (2001).

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Williamsite, on other hand, exhibits Greasy, Resinous, Silky and Waxy luster.
