Holmquistite Vs Moroxite Fracture
Fracture is an important parameter when you compare Holmquistite and Moroxite Physical Properties. It is necessary to understand the significance of these properties, before you compare Holmquistite Vs Moroxite 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. Moroxite fracture is ConchoidalArthur Thomas, ConchoidalArthur Thomas, Gemstones (2009) and Gemstones (2009).
