When it comes to choosing the best pick among Gems for Sagittarius gemstones, Sodalite is known to be a popular choice!Physical properties of Sodalite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Sodalite 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. Sodalite cleavage is nothing but the plane across which the crystal splits during cutting. Sodalite cleavage is Poor on ,and specific gravity of Sodalite is 2.15-2.40.
The physical properties of Sodalite, 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 Sodalite is represented by Na8Al6Si6O24Cl2.
