It is necessary to understand the significance of these properties, before you compare Vishnevite Vs Boulder 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 Vishnevite is Brittle and Uneven. Boulder Opal fracture is ConchoidalArthur Thomas, ConchoidalArthur Thomas, ConchoidalArthur Thomas, Gemstones (2009), Gemstones (2009) and Gemstones (2009).
