Cordierite Vs Riebeckite Fracture
Fracture is an important parameter when you compare Cordierite and Riebeckite Physical Properties. It is necessary to understand the significance of these properties, before you compare Cordierite Vs Riebeckite 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 Cordierite is Brittle, Conchoidal and Subconchoidal. Riebeckite fracture is Brittle, Splintery and Uneven.
Cordierite Vs Riebeckite Luster
A primary knowledge about Cordierite vs Riebeckite 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. Cordierite exhibits Greasy and Vitreous luster. Riebeckite, on other hand, exhibits Silky and Vitreous luster.
