WebMicas: Muscovite and Biotite The mica minerals have one perfect cleavage that allows them to be broken into very thin sheets. This is very distinctive. Muscovite is clear, silvery, or coppery silver in color (depending on the thickness of the sample and presence of impurities) whereas fresh biotite is black.
