Strontianite Vs Cordierite Iolite Fracture
Fracture is an important parameter when you compare Strontianite and Cordierite Iolite Physical Properties. It is necessary to understand the significance of these properties, before you compare Strontianite Vs Cordierite Iolite 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 Strontianite is Brittle, Conchoidal, ConchoidalAnthony et al, Handbook of mineralogy (2001), Uneven and Uneven. Cordierite Iolite fracture is ConchoidalWalter Schumann, Gemstones of the world (2001), Uneven and Uneven.
Strontianite Vs Cordierite Iolite Luster
A primary knowledge about Strontianite vs Cordierite Iolite 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. Strontianite exhibits Greasy and Vitreous luster. Cordierite Iolite, on other hand, exhibits Vitreous luster.
