When it comes to choosing the best pick among Semi Precious Gemstones gemstones, Moonstone is known to be a popular choice!Physical properties of Moonstone include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Moonstone 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. Moonstone cleavage is nothing but the plane across which the crystal splits during cutting. Moonstone cleavage is 2,1 basal ; 2,1 prismatic ; 3,1 pinacoidal,and specific gravity of Moonstone is 2.56-2.60.
The physical properties of Moonstone, 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 Moonstone is represented by Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8.
