This class may show the cube, octahedron, and rhombic dodecahedron, but the
only characteristic form in this class is the pyritohedron. The lower symmetry in
this class can be observed in the striations found on the cube face, which
alternate ...

Its most common associate among the gangue minerals is quartz. The
pyritohedron is the most commonly observed form where crystals are well formed
, though the cube is also common. Leadville is famous among mineralogists for
its large, ...
