Wiccan Moonsong: Chalcopyrite - Peacock Ore Chalcopyrite is a crystallized copper iron sulfide mineral. Chalcopyrite Peacock Ore is the name given to Chalcopyrite samples that have the presence of bornite, a sulfide mineral that gives the stone an iridescent blue and purple and red tarnish. This effect can also be artificially achieved by enhancing the stone with acid. You will often find Peacock Ore being sold as Bornite, when a lot of times it is Chalcopyrite which is more common to find.
