Lattice Systems

One possible way of categorizing crystals is by the symmetry of their lattice. Where a crystal system is one of seven ways to categorize crystals based on the symmetry of the crystal (cubic, hexagonal, trigonal, tetragonal, orthorhombic, monoclinic, triclinic), a lattice system is one of seven ways to categorize crystals based on the symmetry of their lattice (cubic, hexagonal, rhombohedral, tetragonal, orthorhombic, monoclinic, triclinic).
