Cobaltite Vs Hardystonite Fracture
Fracture is an important parameter when you compare Cobaltite and Hardystonite Physical Properties. It is necessary to understand the significance of these properties, before you compare Cobaltite Vs Hardystonite 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 Cobaltite is Brittle, Handbook of mineralogy (2001) More from other references, Handbook of mineralogy (2001) More from other references, Metallic, UnevenAnthony et al and UnevenAnthony et al. Hardystonite fracture is Brittle and Metallic.
Cobaltite Vs Hardystonite Luster
A primary knowledge about Cobaltite vs Hardystonite 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. Hardystonite, on other hand, exhibits Greasy, Resinous and Vitreous luster.
