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

A primary knowledge about Topaz vs Alexandrite 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. Topaz exhibits Vitreous luster. Alexandrite, on other hand, exhibits Vitreous luster.
