Crystallography and Minerals Arranged by Crystal Form
This table summarizes the 32 crystal classes by crystal system and class name, including symmetry elements. Clicking on each system or class heading provides information on each class within the system, including axes of rotation, symmetry planes, center, and Hermann-Maugin symbols. There is also an illustration, paper models that can be downloaded, printed and assembled, animated pop-ups that show the complete symmetry as the model is rotated, and a listing of mineral species in the class.
