Alexandrite Vs Andalusite Fracture

Fracture is an important parameter when you compare Alexandrite and Andalusite Physical Properties. It is necessary to understand the significance of these properties, before you compare Alexandrite Vs Andalusite 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. Andalusite fracture is Uneven, Subconchoidal and Splintery.

A primary knowledge about Alexandrite vs Andalusite luster is useful in apparent identifications of these gemstones.

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Alexandrite exhibits Vitreous luster. Andalusite, on other hand, exhibits Vitreous and Greasy luster.
