Danburite Vs Chrysoberyl Fracture
Fracture is an important parameter when you compare Danburite and Chrysoberyl Physical Properties. It is necessary to understand the significance of these properties, before you compare Danburite Vs Chrysoberyl 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 Danburite is Uneven, Uneven, ConchoidalWalter Schumann, Gemstones of the world (2001) More from other references, Conchoidal and Brittle. Chrysoberyl fracture is Uneven, Conchoidal to uneven, Brittle, Metallic, Uneven, ConchoidalWalter Schumann, Brittle and Metallic.
