Alexandrite Vs Malachite Fracture

Fracture is an important parameter when you compare Alexandrite and Malachite 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.

Malachite, on other hand, exhibits Adamantine, Fibrous, Silky and Vitreous luster.
