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 Rosasite is Splintery.

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Rosasite exhibits Silky and Vitreous luster.
