When it comes to choosing the best pick among Colorless Gems gemstones, Muscovite is known to be a popular choice!Physical properties of Muscovite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Muscovite 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. Muscovite cleavage is nothing but the plane across which the crystal splits during cutting. Muscovite cleavage is Perfect on the ,and specific gravity of Muscovite is 2.78-2.88.
The physical properties of Muscovite, 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 Muscovite is represented by KAl 2AlSi 3O 10(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references.
