It is often associated with Native Copper, Malachite, Azurite, Limonite and Chalocite.
Of all the copper ores except for native copper, Cuprite gives the greatest yield of copper per molecule since there is only one oxygen atom to every two copper atoms. As a mineral specimen, Cuprite shows fine examples of well-developed cubic crystal forms. Cuprite’s dark crystals show internal reflections of the true deep red inside the almost black crystal.
