Cassiterite Vs Smithsonite Fracture
Fracture is an important parameter when you compare Cassiterite and Smithsonite Physical Properties. It is necessary to understand the significance of these properties, before you compare Cassiterite Vs Smithsonite 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 Cassiterite is ConchoidalArthur Thomas, Gemstones (2009), Irregular, Subconchoidal and Uneven. Smithsonite fracture is Brittle, Gemstones of the world (2001) More from other references, Metallic, Sub-Conchoidal, Uneven and UnevenWalter Schumann.
Cassiterite Vs Smithsonite Luster
A primary knowledge about Cassiterite vs Smithsonite 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. Cassiterite exhibits Adamantine and Greasy luster. Smithsonite, on other hand, exhibits Pearly and Vitreous luster.
