When it comes to choosing the best pick among Colorless Gems gemstones, Orthoclase is known to be a popular choice!Physical properties of Orthoclase include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Orthoclase 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. Orthoclase cleavage is nothing but the plane across which the crystal splits during cutting. Orthoclase cleavage is Has perfect cleavage on and good cleavage on . Cleavages intersect at 90°.,and specific gravity of Orthoclase is 2.54-2.61.
The physical properties of Orthoclase, 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 Orthoclase is represented by KAlSi 3O 8Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
