Bornite

Bornite is an ore of copper. It is made of copper and iron sulfides. It has the chemical formula Cu5FeS4. It contains more copper and less iron than chalcopyrite.

It looks like chalcopyrite. The two are both sometimes called "peacock color" or "peacock ore" because of their colourful tarnish.[1]
