Antigorite Vs Danburite Fracture
Fracture is an important parameter when you compare Antigorite and Danburite Physical Properties. It is necessary to understand the significance of these properties, before you compare Antigorite Vs Danburite 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 Antigorite is Brittle, Conchoidal, Conchoidal, Handbook of mineralogy (2001) and Metallic. Danburite fracture is Brittle, Conchoidal, ConchoidalWalter Schumann, Gemstones of the world (2001) More from other references, Uneven and Uneven.
Antigorite Vs Danburite Luster
A primary knowledge about Antigorite vs Danburite 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. Antigorite exhibits Greasy, Resinous, Silky and Waxy luster. Danburite, on other hand, exhibits Greasy and Vitreous luster.
