fluorite-octahedron cleavage
Fluorite is one of the few minerals that have four directions of cleavage. If a crystal of fluorite is
carefully cleaved so that the resulting form has faces of equal size and shape, an octahedron with
8 faces is formed. Miners who worked in the Cave-in-Rock fluorite district of southern Illinois used
to spend their free time during lunch hours cleaving fluorite into collectible octahedrons.
