Web6.3 Crystal systems. Most three-dimensional lattices display some symmetry, although the symmetry elements (e.g. rotation axes and mirror planes) can be in any direction. Some arrangements of symmetry elements place special constraints on the shape of the unit cell. For example, a four-fold rotation axis requires the unit cell to have a square ... Web3.1 Crystal shape. Well-developed crystals show a number of flat faces and a distinct shape.
