Stibiotantalite Vs Anhydrite Fracture
Fracture is an important parameter when you compare Stibiotantalite and Anhydrite Physical Properties. It is necessary to understand the significance of these properties, before you compare Stibiotantalite Vs Anhydrite 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 Stibiotantalite is ConchoidalAnthony et al, Handbook of mineralogy (2001), Brittle and Conchoidal. Anhydrite fracture is Conchoidal, Brittle, UnevenArthur Thomas and Gemstones (2009).
Stibiotantalite Vs Anhydrite Luster
A primary knowledge about Stibiotantalite vs Anhydrite 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. Stibiotantalite exhibits Adamantine luster. Anhydrite, on other hand, exhibits Pearly and Greasy luster.
