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 Precious Opal is Conchoidal, Conchoidal and Gemstones of the world (2001) More from other references. Polyhalite fracture is Brittle and Conchoidal.
Precious Opal Vs Polyhalite Luster
