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.

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.

Found in 1990-92

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.
Few specimens were obtained and, at first, it was thought that by their shapes and color tones they were marcasite, but further analysis characterized them as pyrolusite. Probably the best pyrolusite Spanish specimens.

This sample is one of the first amethyst quartz specimens were found in the Les Mallorquines area, near of the well known quartz crystals area of Sils and Massabé quarry. They come from outcrops and not of any mining works. The crystal is a floater and is partially recrystallized. It shows well developed rhombohedral terminal faces and, as usual, some bright faces and other dull. Good transparence. A historical specimen from this area found in the middle 80's.

The colorless crystals of fluorite from Emilio mine are well known and show a hyaline transparency. It is hard to capture their brilliance with the camera. This specimen shows a cubic crystal druse with forms of the trapezohedron at the vertices. With some inclusions. Few crystals show small notches on the edges, very common in Emilio fluorite crystals because of its sensitivity to temperature changes, but without affecting their beauty.
A brilliant miniature!
