Great, looks like Quartz crystals, or a mineral called Berlinite. If you want to have some fun playing with the crystal structure, as occurs in nature, you can vary one of the termination faces by making it larger (offsetting), one or 3 of the side faces, or a growth phenomena called 'ghosting' where the outline of earlier growth phases are visible (Smokey quartz from Colorado does this), or a 'negative crystal' which is a cavity in the inverse shape of a crystal (Herkimer diamonds do this). If your crystals are in the cubic system, you very often see 'skeletal' growth where the edges thicken, but growths stops on the center during the last phase of growth, and often see corners 'cut' giving partial octohedrons (gold), or in some cases dodecahedrons (Diamond)
