TitleBornite from Oscola Mine, Mississippi
DescriptionThis specimen of bornite is 9 cm across. Bornite, Cu5FeS4 (copper iron sulfide), is an important copper ore mineral. It rarely forms good crystals; massive samples such as the one shown are typical. Although coppery red to brown on fresh surfaces, bornite readily tarnishes to iridescent purple. It is sometimes called peacock ore because of its color.
