This collection features Chalcopyrite specimens recognised for their brassy yellow colour and metallic lustre. Chalcopyrite is a copper iron sulphide mineral that forms in hydrothermal veins and igneous environments, often associated with Quartz and other sulphide minerals.

Chalcopyrite is valued for its crystalline form, surface iridescence and importance as a primary copper ore. It commonly occurs as massive material or well formed crystals with a distinctive tarnish that can develop natural rainbow hues. This collection highlights Chalcopyrite pieces that display clear metallic character, crystal structure and authentic sulphide formation.
