When it comes to choosing the best pick among Green Gemstones gemstones, Dioptase is known to be a popular choice!Physical properties of Dioptase include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Dioptase 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. Dioptase cleavage is nothing but the plane across which the crystal splits during cutting. Dioptase cleavage is Perfect in three directions,and specific gravity of Dioptase is 3.25-3.35.
The physical properties of Dioptase, 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 Dioptase is represented by CuSiO 2(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
