GERSDORFFITE (Nickel Arsenic Sulfide) - Amethyst Galleries

This is the lowest symmetry class of the isometric system and contains only three fold and two fold axes. Most gersdorffite has an unordered arsenic-sulfur structure and therefore belongs to the higher Diploidal symmetry class. Gersdorffite is very similar to a nickel antimony sulfide called ullmannite.
