When it comes to choosing the best pick among Precious Gemstones gemstones, Diamond is known to be a popular choice!Physical properties of Diamond include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Diamond 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. Diamond cleavage is nothing but the plane across which the crystal splits during cutting. Diamond cleavage is 111 (perfect in four directions),and specific gravity of Diamond is 3.50-3.53.
The physical properties of Diamond, 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 Diamond is represented by C.
