Hurlbutite Vs Milk Opal Fracture
Fracture is an important parameter when you compare Hurlbutite and Milk Opal Physical Properties. It is necessary to understand the significance of these properties, before you compare Hurlbutite Vs Milk Opal 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 Hurlbutite is Brittle, Conchoidal, ConchoidalAnthony et al, ConchoidalAnthony et al, Handbook of mineralogy (2001) and Handbook of mineralogy (2001). Milk Opal fracture is Conchoidal.
