This is a natural chalcopyrite mineral specimen from Daye, China, a region well known for its historic copper deposits.
The surface displays natural rainbow metallic tones — green, gold, blue, and subtle iridescent highlights — created through natural oxidation over time, not artificial coating.
The crystal layer forms a fine-grained, sparkling texture that flows organically across the reddish host rock, giving the piece a sculptural, landscape-like presence.
Unlike polished crystals or treated “peacock ore,” this specimen remains raw, untreated, and authentic, making it ideal for mineral collectors, geology enthusiasts, and modern interior display.
