Kyanite Vs Apatite Fracture
Fracture is an important parameter when you compare Kyanite and Apatite Physical Properties. It is necessary to understand the significance of these properties, before you compare Kyanite Vs Apatite 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 Kyanite is Splintery, Brittle and Metallic. Apatite fracture is Conchoidal, Uneven, Conchoidal, Brittle, ConchoidalArthur Thomas, Gemstones (2009) and Conchoidal to uneven.
