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