Pearl Cleavage
When it comes to choosing the best pick among Organic gemstones, Pearl is known to be a popular choice!Physical properties of Pearl include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Pearl 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. Pearl cleavage is nothing but the plane across which the crystal splits during cutting. Pearl cleavage is none,and specific gravity of Pearl is 2.60-2.85.
The physical properties of Pearl, 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.
