Mica History Mica is a natural stone with a vitreous to pearly luster, which forms in multiple distinct layers. Mica is actually a broad term that is attributed to more than 34 types of these layers. The most common form of mica is called muscovite, while other varieties include anandite, fuchsite and lepidolite.
The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible. Layering in the divalent, or brittle, micas
