Laminar growth of deformed and flattened native copper crystals. 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.

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.

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.

A huge size specimen formed by several groups of brilliant sphalerite crystals, showing a perfect brilliance and curved faces and edges. Transparence is quite good and shows toasted honey tones. Accompanied by several dolomite rhombohedrons on matrix.
Troya Mine was closed in 1993, only a few years before these specimens were collected in 1990. Nowadays the mine is collapsed and flooded. This specimen was in a former German mineral collection since then.

Group of very sharp pyromorphite crystals with a hexagonal shape and the characteristic color. The crystals fill cavities of the matrix. Mine has became a classic Spanish for pyro.

Group of hexagonal pr¡smatic crystals showing a good brilliance, characteristic color and very well defined faces and edges. From a classic Spanish mine.

A miniature formed by a druse of translucent and brilliant hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. These specimens have been determined by isotopic studies with equal results to those of this mine. This sample is from an old German mineral collection.

In this miniature we can enjoy two sides. One is covered by several hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. In the other side, small aggregates of transparent and sharp hexagonal pyro crystals partially covered by black coronadite or growing on it. These specimens have been determined by isotopic studies with equal results to those of this mine. Very curious specimen. This sample is from an old German mineral collection.

Groups of brilliant and sharp hexagonal pyromorphite crystals, with a fibrous shape due to parallel growths. Color beige, a little bit green. On a quartz matrix. These specimens have been determined by isotopic studies with equal results to those of this mine. This sample is from an old German mineral collection.

Groups of brilliant hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. On a matrix of minute quartz crystals.

A very rich pyromorphite druse formed by several hexagonal shape crystals. Some of them show parallel growths and fibrous like forms. With a marked color zoning that varies between grass green in the center to beige-green on terminal pinacoid. These specimens have been determined by isotopic studies with equal results to those of this mine. This excellent sample is from an old German mineral collection.

A very brilliant specimen of this classic Basque mine. It shows a sphalerite matrix partially covered with brilliant sphalerite crystals, with slightly curved faces and edges. Good transparency and toasted honey color. It is accompanied by several greenish siderite rhombohedral crystals (up to 9 mm.), with some dolomite. A very aesthetic specimen.

This sample shows two mineralized sides. A first one totally covered by brilliant sphalerite crystals, with complex and curved faces and edges. Good transparence with toasted honey tones. Accompanied by few crystals of siderite. The other specimen side is partially covered by several yellowish-white dolomite crystals and flattened, brilliant and defined rhombohedrons of siderite with greenish tones.

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!

In this brilliant spoecimen we can enjoy some groups of cubic crystals of fluorite with defined edges and echeloned growths on faces. With an excellent transparence and a marked geometric color zoning, from colorless to violet and purple. Fluorite crystals are disposed on a matrix partially covered by small but bright quartz crystals and some tabular barite. An oldie from this mine.

Group of cubic crystals of fluorite, some bevelled by rhombododecahedron, transparent, brilliant, defined and more intense color zoning in the crystal core. Deep violet to purple tones, according to incident light. It is accompanied by quartz and barite crystals clearly visible on the back side. A Spanish classic from a old German collection.

Cobaltoan calcite specimen showing carbonate growths with colours between magenta and yellow, typical for this classic Catalan mine. The mineralization is filling fissures of the Triassic conglomerates. Nowadays mine is partially collapsed and restored and it is impossible to get specimens. This sample is from a previous single finding before shaft was filled and some galleries restored.

A nice cobaltoan calcite specimen showing concretionary growths with a good and deep colour. The mineralization is filling fissures of the Triassic conglomerates, which are very visible in this specimen. Main side shows a polished section where we can enjoy perfectly banded purple calcite and conglomerate individual clasts. Nowadays mine is partially collapsed and restored and it is impossible to get specimens.
