Opal Vs Smoky Quartz Fracture
Fracture is an important parameter when you compare Opal and Smoky Quartz Physical Properties. It is necessary to understand the significance of these properties, before you compare Opal Vs Smoky Quartz 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 Opal is Brittle, Conchoidal, Conchoidal and Gemstones of the world (2001) More from other references. Smoky Quartz fracture is Conchoidal, ConchoidalWalter Schumann and Gemstones of the world (2001).
Opal Vs Smoky Quartz Luster
A primary knowledge about Opal vs Smoky Quartz 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. Opal exhibits Pearly and Vitreous luster. Smoky Quartz, on other hand, exhibits Vitreous luster.
