When it comes to choosing the best pick among Gems for Leo gemstones, Sunstone is known to be a popular choice!Physical properties of Sunstone include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Sunstone 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. Sunstone cleavage is nothing but the plane across which the crystal splits during cutting. Sunstone cleavage is 001,and specific gravity of Sunstone is 2.62-2.65.
The physical properties of Sunstone, 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 Sunstone is represented by Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8.
