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

Tantalite Vs Alexandrite Luster

A primary knowledge about Tantalite vs Alexandrite luster is useful in apparent identifications of these gemstones. Luster is the measure of light that gets reflected when incident on a finished cut gemstone. There are two major types of lusters: Silky and Adamantine. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Tantalite exhibits Resinous luster. Alexandrite, on other hand, exhibits Vitreous luster.
