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