The mineral mica is not a gemstone. It is not considered a precious mineral or gem. It is a valuable mineral that has a number of applications, and it is likely you have some mica in your home now. Mica is used in the electronics industry as an insulator beneath semiconductor packages when they are mounted on heat sinks in consumer (and other) electronic equipment.
The ore of mica is called "muscovite." It is a type of mica mineral that is commonly found in metamorphic and igneous rocks. Muscovite is known for its pearlescent luster and excellent cleavage properties.
Muscovite (clear) and Biotite (black) are the commonest mica forms. Fuchsite (green) is an unusual mica containing chromium. Please see the related link below for a listing of the mica group of minerals.
Biotite mica has a Mohs hardness of 2.5-3.0.
Mica meets all of the requirements of a mineral; solid, naturally occurring, crystalline structure, specific range of chemical formulae, and inorganic.

no it is a mineral
Mica has perfect basal cleavage.
Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
Both feldspar and mica are silicates.
