Paramelaconite is a rare black-colored copper oxide mineral with formula Cu21+Cu22+O3 (or Cu4O3). It was discovered in the Copper Queen Mine in Bisbee Arizona about 1890. It was described in 1892 and more fully in 1941. Its name is derived from the Greek word for near and the similar mineral melaconite now known as tenorite.
