Biotite cleaveage
Web1 Biotite and muscovite belong to a family of platy minerals called “mica”. All have one strong cleavage and form sheets that you can pick apart with a knife or your fingernail. Micas strongly reflect light and appear shiny. Muscovite is also called “white mica” and biotite is sometimes called “brown mica” or “black mica”. WebGemstone Cleavage Chart. One of the characteristics of crystals is that they have cleavage. Cleavage is the tendency of a crystal to break cleanly along distinct planes. Since most gemstones are crystals, cleavage is an issue that gem buyers as well as jewelers and gem cutters need to take into account. Minerals can have from one to five ...
