Paramelaconite: History, Description and occurrence & Synthesis

Paramelaconite is a rare, black-colored copper(I,II) oxide mineral with formula CuI2CuII2O3 (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.
