How do you identify the mineral mica?

Answer 1

Mica appears as sheety, shiny, plated crystals, sometimes displaying as 'books', where each cleavage plane is easily separated by a knife blade. Mica is also on the low end of the Mohs hardness scale, at 2-2.5, so you can probably scratch it with your fingernail. Mica is often found in association with granite, or granite pegmatites.

Answer 2

Mica can be identified by its thin, sheet-like structure and its ability to peel into thin, transparent layers. It also has a pearly or vitreous luster and is commonly found in shades of brown, green, or silver. Mica is typically softer than glass and can be easily scratched with a fingernail.

Answer 3

clear shiny crystal with perfect parallel cleavage. Larger sheets of it were used for windows hence the name Muscovite.
