Number of faces: 24 A crystal's defining feature is its unique arrangement of faces, all linked through a shared bond to the crystal's underlying symmetry operations - the crystal's inherent symmetry plays a direct role in determining which specific forms come into existence. There are 48 possible crystal forms (47 forms as defined by the Fedorov Institute's crystallographers, see https://skfb.ly/6VyCs) that can emerge from the 32 distinct combinations of symmetry operations.
