Muscovite is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage, yielding remarkably thin laminæ that are often highly elastic. It can be colorless or tinted through grays, violet, or red, and can be transparent or translucent. Fuchsite and mariposite are green varieties of muscovite, owing their green color to chromium impurities. Alurgite is a manganese-bearing, purple to reddish variety of muscovite.
