When it comes to choosing the best pick among gemstones, Sellaite is known to be a popular choice!Physical properties of Sellaite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Sellaite 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. Sellaite cleavage is nothing but the plane across which the crystal splits during cutting. Sellaite cleavage is Perfect on and ,and specific gravity of Sellaite is 3.14-3.16.
The physical properties of Sellaite, 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 Sellaite is represented by MgF 2Ulrich Henn and Claudio C..
