Periclase Vs Astrophyllite Fracture

Fracture is an important parameter when you compare Periclase and Astrophyllite Physical Properties.

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 Periclase is Brittle and Conchoidal.

Astrophyllite, on other hand, exhibits Greasy and Pearly luster.
