Schorl Vs Tourmaline Bi Color Fracture
Fracture is an important parameter when you compare Schorl and Tourmaline Bi Color Physical Properties. It is necessary to understand the significance of these properties, before you compare Schorl Vs Tourmaline Bi Color 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 Schorl is Brittle, Conchoidal, ConchoidalAnthony et al, Handbook of mineralogy (2001), Uneven and Uneven.
