Cassiterite Vs Emerald Fracture
Fracture is an important parameter when you compare Cassiterite and Emerald Physical Properties. It is necessary to understand the significance of these properties, before you compare Cassiterite Vs Emerald 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 Cassiterite is ConchoidalArthur Thomas, Gemstones (2009), Irregular, Subconchoidal and Uneven. Emerald fracture is ConchoidalWalter Schumann, Gemstones of the world (2001), Uneven and Uneven.
