Aventurine Vs Black Opal Fracture
Fracture is an important parameter when you compare Aventurine and Black Opal Physical Properties. It is necessary to understand the significance of these properties, before you compare Aventurine Vs Black Opal 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 Aventurine is Conchoidal. Black Opal fracture is ConchoidalArthur Thomas, ConchoidalArthur Thomas, Gemstones (2009) and Gemstones (2009).
Aventurine Vs Black Opal Luster
A primary knowledge about Aventurine vs Black Opal 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. Aventurine exhibits Vitreous luster.
