Datolite Vs Vivianite Fracture
Fracture is an important parameter when you compare Datolite and Vivianite Physical Properties. It is necessary to understand the significance of these properties, before you compare Datolite Vs Vivianite 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 Datolite is Conchoidal, Uneven, ConchoidalArthur Thomas, Gemstones (2009), Brittle and Metallic. Vivianite fracture is (e.g. graphite)..
Datolite Vs Vivianite Luster
A primary knowledge about Datolite vs Vivianite luster is useful in apparent identifications of these gemstones.
