Vivianite Cleavage
When it comes to choosing the best pick among Blue Gemstones gemstones, Vivianite is known to be a popular choice!Physical properties of Vivianite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Vivianite Optical Properties are responsible for imparting various physical properties to its structure. Knowledge of these properties is equally important to gem-cutters as well as to consumers. Vivianite cleavage is nothing but the plane across which the crystal splits during cutting. Vivianite cleavage is Perfect,and specific gravity of Vivianite is 2.64-2.70.
The physical properties of Vivianite, in fact, are imparted by the chemical composition of its individual molecule. The reactivity or inertness of the crystal is solely governed by its chemical structure. Chemical composition of Vivianite is represented by Fe 3(PO 4) 2 8H 2OUlrich Henn and Claudio C..
