Norbergite Vs Precious Opal Fracture
Fracture is an important parameter when you compare Norbergite and Precious Opal Physical Properties. It is necessary to understand the significance of these properties, before you compare Norbergite Vs Precious Opal 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 Norbergite is Brittle, Conchoidal, ConchoidalAnthony et al, Handbook of mineralogy (2001), Uneven and Uneven. Precious Opal fracture is Conchoidal, Conchoidal and Gemstones of the world (2001) More from other references.
Norbergite Vs Precious Opal Luster
A primary knowledge about Norbergite vs Precious Opal 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. Norbergite exhibits Vitreous luster.
