Diagram showing the seven primitive crystal systems with labeled 3D shapes: isometric (cubic), tetragonal, orthorhombic, hexagonal, triclinic, monoclinic, and rhombohedral (trigonal), each with axis orientation and a brief description of their geometric properties.

monoclinic crystal system

Three illustrated crystals are shown to demonstrate different crystal classes and symmetries: a tall, prismatic monoclinic gypsum crystal; a pointed, double-ended tetragonal wulfenite crystal; and a cubic isometric halite crystal, each labeled with its crystal class and symmetry content.
