Chalcopyrite is a copper iron sulphide mineral that crystallizes in the tetragonal system. It has a brassy to golden yellow colour and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green tinged black. On exposure to air, chalcopyrite oxidises to a variety of oxides, hydroxides and sulphates.

Treated chalcopyrite are specimens that have been treated with acid to give them a blue and purple iridescence, which enhances their visual appeal. In nature the surface of chalcopyrite loses its metallic luster and brass-yellow colour upon weathering. It tarnishes to a dull, grey-green colour, but in the presence of acids the tarnish can develop a red to blue to purple iridescence.

**WarningContains copper which can cause serious health issues if not handled correctly. DO NOT hammer or break this rock up.
