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