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 Vlasovite is Conchoidal and Brittle. Datolite fracture is Conchoidal, Uneven, ConchoidalArthur Thomas, Gemstones (2009), Brittle and Metallic.

Luster is the measure of light that gets reflected when incident on a finished cut gemstone. There are two major types of lusters: Silky and Adamantine. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Vlasovite exhibits Greasy, Vitreous and Pearly luster. Datolite, on other hand, exhibits Vitreous luster.
