When it comes to choosing the best pick among Green Gemstones gemstones, Grossular is known to be a popular choice!Physical properties of Grossular include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Grossular 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. Grossular cleavage is nothing but the plane across which the crystal splits during cutting. Grossular cleavage is none,and specific gravity of Grossular is 3.55-3.73.
The physical properties of Grossular, 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 Grossular is represented by Ca 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009).
