When it comes to choosing the best pick among Green Gemstones gemstones, Glass is known to be a popular choice!Physical properties of Glass include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Glass 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. Glass cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Glass is 2.39-4.00.
The physical properties of Glass, 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.
