Astrophyllite Vs Natrolite Fracture

Fracture is an important parameter when you compare Astrophyllite and Natrolite Physical Properties. It is necessary to understand the significance of these properties, before you compare Astrophyllite Vs Natrolite 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. Natrolite fracture is Brittle, Gemstones (2009), Metallic and Uneven.
