WebCrystal form refers to the geometric shape of mineral crystals. Crystal form is caused by the symmetrical, three-dimensional arrangement of atoms inside the mineral. The arrangement of atoms in a mineral controls the shape of the mineral. The left photograph shows how quartz fits in the hexagonal crystal system. WebThe structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions.
