Gahnospinel Vs Unakite Fracture
Fracture is an important parameter when you compare Gahnospinel and Unakite Physical Properties. It is necessary to understand the significance of these properties, before you compare Gahnospinel Vs Unakite 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 Gahnospinel is ConchoidalArthur Thomas and Gemstones (2009).
Gahnospinel Vs Unakite Luster

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Gahnospinel exhibits Vitreous luster.
