Isometric system

The isometric (or cubic) crystal system has three axes of symmetry, all at right angles to one another and all of equal length.

Crystals are generally blocky in appearance or ball-like, with many similar, symmetrical faces; characteristic forms are cubes, octahedronss, and dodecahedrons, either single or in varied combinations.
