When it comes to choosing the best pick among Grey Gemstones gemstones, Gibbsite is known to be a popular choice!Physical properties of Gibbsite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Gibbsite 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. Gibbsite cleavage is nothing but the plane across which the crystal splits during cutting. Gibbsite cleavage is Perfect,and specific gravity of Gibbsite is 2.35.
The physical properties of Gibbsite, 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 Gibbsite is represented by Al(OH)3.
