Chalcopyrite 155g — Moonta, South Australia

Fool's Gold's More Colourful Cousin — From South Australia's Copper Coast

This excellent chalcopyrite specimen hails from Moonta in South Australia — a town steeped in copper mining history and part of the celebrated Yorke Peninsula copper triangle, once one of the most productive copper mining regions in the British Empire. Chalcopyrite from Moonta carries outstanding historical and mineralogical provenance.

Chalcopyrite is a copper iron sulphide mineral and the world's most important copper ore. Its brassy yellow metallic lustre often develops a spectacular iridescent tarnish — shifting through peacock blues, purples, greens, and golds — making it one of the most visually dazzling metallic minerals in any collection. At 155g this is a substantial specimen with excellent character.
