Gibbsite Vs Tourmaline Fracture

Fracture is an important parameter when you compare Gibbsite and Tourmaline Physical Properties. It is necessary to understand the significance of these properties, before you compare Gibbsite Vs Tourmaline 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 Gibbsite is Fibrous. Tourmaline fracture is Uneven and Conchoidal.

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Gibbsite exhibits Vitreous and Pearly luster. Tourmaline, on other hand, exhibits Vitreous luster.
