Key Differences
- ◆ Chalcopyrite is deeper, more brassy-yellow than pyrite's paler brass-yellow color.
- ◆ Pyrite is harder (6–6.5) than chalcopyrite (3.5–4); chalcopyrite can be scratched with a knife.
- ◆ Chalcopyrite has a greenish-black streak; pyrite has a greenish-black to brownish-black streak.
- ◆ Chalcopyrite is the most important copper ore (CuFeS2); pyrite is an iron sulfide (FeS2).
- ◆ Chalcopyrite often shows iridescent tarnish (peacock ore); pyrite typically stays bright.
