Superb old specimen of native copper and cuprite. This nodule consists of cuprite and malachite covered with copper, apparently, although the appearance of the two minerals is quite similar.
Copper and cuprite from the Atacama desert in Chile. The copper deposits are numerous.
Specimen from the naturalist dealer Deyrolle of Paris, probably dated from the end of the XIXth, beginning of the XXth century. Comes with label and original box.
