Afghanite Vs Atacamite Fracture
Fracture is an important parameter when you compare Afghanite and Atacamite Physical Properties. It is necessary to understand the significance of these properties, before you compare Afghanite Vs Atacamite 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 Afghanite is Brittle, Brittle, Conchoidal, Conchoidal, Conchoidal, ConchoidalArthur Thomas and Gemstones (2009). Atacamite fracture is Brittle, Conchoidal and Conchoidal.
Afghanite Vs Atacamite Luster
