It is necessary to understand the significance of these properties, before you compare Opal Vs Zinnwaldite 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 Conchoidal, Conchoidal, Gemstones of the world (2001) More from other references and Brittle. Zinnwaldite fracture is Uneven.
