Gahnospinel Vs Friedelite Fracture
Fracture is an important parameter when you compare Gahnospinel and Friedelite Physical Properties. It is necessary to understand the significance of these properties, before you compare Gahnospinel Vs Friedelite 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 Gahnospinel is ConchoidalArthur Thomas and Gemstones (2009). Friedelite fracture is Brittle, Gemstones (2009) Tough, Gemstones (2009) Tough, Uneven, UnevenArthur Thomas and UnevenArthur Thomas.
