Topaz Vs Amethyst Fracture
Fracture is an important parameter when you compare Topaz and Amethyst Physical Properties. It is necessary to understand the significance of these properties, before you compare Topaz 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 Topaz is Brittle, ConchoidalArthur Thomas, Gemstones (2009), Subconchoidal and Uneven. Amethyst fracture is Conchoidal, ConchoidalWalter Schumann and Gemstones of the world (2001).
