Mica is a mineral group known for its distinctive layered silicate structure, which yields perfect basal cleavage and thin, flexible sheets. The sheets often display a pearly to vitreous luster and can be colorless, brown, or shades of gray, green, or black depending on the exact member of the group. Common forms include muscovite and biotite, sometimes presenting chatoyancy or a subtle iridescence in good specimens. In hand specimens, mica typically forms in mica schist or pegmatites, and crystals can be mined in relatively large, flat flakes that separate along the perfect cleavage planes.

About Mica
Notable sources include Pakistan, Afghanistan, China, Brazil, and Tanzania, where mica crystals and sheets are collected for their clean cleavage and subtle color. Collectors prize well-terminated sheets with bright luster and minimal alteration, as well as historic specimens from classic localities. Although often inexpensive, high-quality sheets or book-like masses can be striking in mineral displays and can serve as useful specimens for understanding mineral structure and the geology of pegmatites and metamorphic rocks.
