Carnelian Vs Tourmaline Fracture
Fracture is an important parameter when you compare Carnelian and Tourmaline Physical Properties. It is necessary to understand the significance of these properties, before you compare Carnelian Vs 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 Carnelian is Conchoidal, Gemstones of the world (2001), Splintery, Uneven and UnevenWalter Schumann. Tourmaline fracture is Conchoidal, ConchoidalArthur Thomas, Gemstones (2009) and Uneven.
Carnelian Vs Tourmaline Luster
A primary knowledge about Carnelian vs 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. Carnelian exhibits Vitreous luster. Tourmaline, on other hand, exhibits Vitreous luster.
