It is necessary to understand the significance of these properties, before you compare Narsarsukite Vs Afghanite 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 Narsarsukite is Brittle, ConchoidalAnthony et al, Handbook of mineralogy (2001), Uneven and Uneven. Afghanite fracture is Brittle, Brittle, Conchoidal, Conchoidal, Conchoidal, ConchoidalArthur Thomas and Gemstones (2009).
Narsarsukite Vs Afghanite Luster
