Muscovite is a silicate mineral that contains potassium and aluminum. It is also known as Mica or Isinglass. Muscovite may form in layers of sheets (called "Books") which are clear with a pearly luster on cleavage faces or as a rock forming mineral found in igneous, metamorphic and sedimentary rocks, often having a flakey, sparkly look.

lepidolite, the most common lithium mineral, basic potassium and lithium aluminosilicate; a member of the common mica group. It is economically important as a major source of lithium. Because it is one of the few minerals containing appreciable amounts of rubidium, it is useful in determining geological age according to strontium–rubidium ratios.

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. When biotite weathers, it can become dark golden or coppery in color.

The Mineral muscovite. Muscovite is the most common form of mica. Its name is derived from "Muscovy Glass", which describes thick sheets of transparent mica that were once used as a glass substitute in Russia. Because of Muscovite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.
