In mineralogy terms the difference between putzite and petzite
is that putzite is an isometric-hextetrahedral iron black mineral containing copper, germanium, silver, and sulfur while petzite is a soft, steel-gray isometric telluride mineral generally deposited by hydrothermal activity and usually associated with rare tellurium and gold minerals.
