Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. Chalcopyrite has a brassy to golden yellow color, which often resembles Gold. However, its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it. Chalcopyrite is a beautiful mineral, with good crystals being fairly common. Chalcopyrite is rarely found in association with native copper.
