The crystals of this group are sub-sheets which usually have elastic ability and their crystallization system is monoclinic and are seen as flexible and resilient scales. The minerals have a specific face and if a blow is made on the surface of the mica group minerals, a six-radial shape is formed. It is insoluble in acids. Other similar minerals are mica.
Muscovite is the most common mica found in granites, pegmatites, gneisses and schists. Muscovites are also known as a contact metamorphic rock or as a secondary mineral material caused by the alteration of topaz, feldspar and kainite.
It has a complex and variable chemical composition and can be seen in green, yellow, white, gray, white colors
The hardness of Muscovite is between 2 and 2.25.
The specific gravity of muscovite is between 2.76 and 3.
