Cubic (crystal system)
In crystallography, the cubic crystal system is the most symmetric of the 7 crystal systems. The system is composed of the three Bravais lattices whose symmetry group is that of a cube.
The three Bravais lattices that form the cubic crystal system are:
| simple cubic | body-centered cubic | face-centered cubic |
| Missing image Cubic_crystal_shape.png Cubic, simple | Missing image Cubic,_body-centered.png Cubic, body-centered | Missing image Cubic,_face-centered.png Cubic, face-centered |
BCC - Body-centered cubic.
FCC - Face-centered cubic.
The point groups that fall under this crystal system are listed below, followed by their representations in international notation and Schoenflies notation, and mineral examples.
| name | international | Schoenflies | example | |
| hexoctahedral | 
| or m3m | Oh | galena |
| gyroidal | 432 | O | cuprite | |
| diploidal | 
| or m3 | Th | pyrite |
| tetrahedral | 
| Td | sphalerite | |
| tetartohedral | 23 | T | ||
