RM427   Native Copper

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

A huge size native copper specimen showing an arborescent growth of deformed crystals. Some of them 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.
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.

RM434   Pyrolusite

Salvadora mine, Cerro el Morante, Calañas, Huelva, Andalucía, Spain

Group of very sharp pyrolusite tabular crystals showing polysynthetic growths, unusual for the species. Good luster, metallic gray color. The echeloned faces gives them a different aesthetics. In the matrix we can observe more classic acicular radiated pyrolusite crystals.
