Euhedral Cuprite Specimen

Cuprite [Cu₂O] is one of the main economic ores of copper. This is a secondary mineral typically formed through the chemical weathering of other copper sulfide minerals.

Although already well known by a range of names, cuprite was officially named in 1845 by Wilhelm Karl von Haidinger from the latin work "cuprum" (which means copper).
