The Dodecahedrons ClipArt gallery includes 23 illustrations of polyhedrons with twelve faces. The term usually references regular dodecahedrons, formed by twelve regular pentagonal faces and three meeting at each vertex. The regular dodecahedron is one of the five Platonic solids.

"This is bounded by twelve pentagonal faces, but these are not regular pentagons, and the angles over the three sets of different edges are different. The regular dodecahedron of geometry, contained by twelve regular pentagons, is not a possible form in crystals." -The Encyclopedia Britannica 1910

"Science has succeeded in classifying the thousands of known crystals in six systems, to each of which belongs a number of forms having some property in common. In order to classify these different crystals, the existence of certain lines within the crystal, called axes, is assumed, around which the form can be symmetrically build up. These axes are assumed to intersect in the center of the crystal, and to pass through from one side to the other." — Hallock, 1905
