Astrophyllite Vs Kyanite Fracture

Fracture is an important parameter when you compare Astrophyllite and Kyanite Physical Properties. It is necessary to understand the significance of these properties, before you compare Astrophyllite Vs Kyanite 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 Astrophyllite is Brittle, Metallic and Uneven. Kyanite fracture is Brittle, Metallic and Splintery.
