It is necessary to understand the significance of these properties, before you compare Demantoid Vs Alexandrite fracture. Whenever a gemstone chip breaks, it leaves a characteristic line along its breakage.

Demantoid Vs Alexandrite Luster

A primary knowledge about Demantoid 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. Demantoid exhibits Adamantine luster. Alexandrite, on other hand, exhibits Vitreous luster.
