Tortoiseshell Vs White Opal Fracture
Fracture is an important parameter when you compare Tortoiseshell and White Opal Physical Properties. It is necessary to understand the significance of these properties, before you compare Tortoiseshell Vs White 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. White Opal fracture is Conchoidal, Conchoidal and Gemstones of the world (2001).
Tortoiseshell Vs White Opal Luster

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria.
