Number of Faces: Four A crystal form is a collective arrangement of faces, each bearing an identical relationship to the functions of symmetry within the crystal — the symmetry inherent in a crystal has a direct impact on which specific forms are present. There exist forty-eight possible crystal forms (forty-seven forms as defined by the crystallographers at the Fedorov Institute; for more information, see https://skfb.ly/6VyCs) that can develop as a result of thirty-two distinct combinations of symmetry.
