Opal Vs Amethyst Fracture
Fracture is an important parameter when you compare Opal and Amethyst Physical Properties. It is necessary to understand the significance of these properties, before you compare Opal Vs Amethyst 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. Amethyst fracture is Conchoidal, ConchoidalWalter Schumann and Gemstones of the world (2001).
