When it comes to choosing the best pick among Gems for Scorpio gemstones, Spinel is known to be a popular choice!Physical properties of Spinel include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Spinel 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. Spinel cleavage is nothing but the plane across which the crystal splits during cutting. Spinel cleavage is None, but may exhibit slight parting,and specific gravity of Spinel is 3.64-3.66.
The physical properties of Spinel, 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 Spinel is represented by MgAl2O4.
