This listing is for a single piece of the exceptionally vibrant mineral Chalcopyrite.
Chalcopyrite, pronounced kal-co-pie-right, is a brassy golden yellow colored copper iron sulfide mineral that crystallizes in the tetragonal system. The name "Chalcopyrite" is derived from the Greek words chalkos, "copper" and pyrites, "strike fire". It is normally brass yellow but may have a purplish blue tarnish. The tarnish can produce a colorful, metallic iridescence and as a result it is often called "peacock ore."
