When it comes to choosing the best pick among Precious Gemstones gemstones, Emerald is known to be a popular choice!Physical properties of Emerald include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Emerald 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. Emerald cleavage is nothing but the plane across which the crystal splits during cutting. Emerald cleavage is Imperfect on the ,and specific gravity of Emerald is 2.67-2.78.
The physical properties of Emerald, 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 Emerald is represented by Be3Al2SiO6.
