Andalusite Vs Diamond Fracture
Fracture is an important parameter when you compare Andalusite and Diamond Physical Properties. It is necessary to understand the significance of these properties, before you compare Andalusite Vs Diamond 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. Diamond fracture is Brittle, Conchoidal, Conchoidal, Conchoidal and Gemstones of the world (2001) More from other references.
