What is Chalcopyrite?
Chalcopyrite is copper iron sulphide, the most important copper ore. Fresh surfaces are brassy yellow; tarnished pieces show iridescent blues and purples (often sold as "peacock ore").
India's copper belts of Khetri (Rajasthan) and Singhbhum (Jharkhand) are chalcopyrite deposits.
Care & cleaning
A softer stone — wipe with a soft, slightly damp cloth, avoid harsh chemicals and knocks, and store separately from harder crystals.
