When it comes to choosing the best pick among Semi Precious Gemstones gemstones, Amethyst is known to be a popular choice!Physical properties of Amethyst include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Amethyst 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. Amethyst cleavage is nothing but the plane across which the crystal splits during cutting. Amethyst cleavage is Indiscernible,and specific gravity of Amethyst is 2.65.
The physical properties of Amethyst, 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 Amethyst is represented by SiO2.
