RM398   Copper

Herrerías mine, Corta Santa Bárbara, Puebla de Guzmán, Huelva, Andalucía, Spain

Arborescent growth of deformed and flattened native copper crystals. Some of them, smaller ones, still show complex cubic forms. Its color is the original and I preferred not alter it by chemical methods. In some of the branches we can see the brilliance of copper, but the rest has this "coppery" tone. It is disposed very aerial on the rocky matrix.
Nowadays the mine is flooded, so get new specimens is quite complicate, if not impossible. A classic mineral specimen from this “Spanish pyrite belt” locality.
