An exceptional specimen composed of several pyrite crystals, one of which stands out for its size, with a very remarkable luster. We observe interesting crystallographic growths that show the cube faces with triglyphic striations and the smooth octahedron faces. It is accompanied by small, lustrous quartz and sphalerite crystals. A very interesting piece from both an aesthetic and crystallographic point of view. The basis of the "Ballon d'Or," awarded annually to the best player in the world, comes from this mine.

Group of pentadodecahedral pyrite crystals on a matrix with small quartz and tennantite crystals. Pyrite shows striated faces and an exceptional luster. In some of the pentadodecahedral pyrite crystals, we can observe edges truncated by the cube faces and some vertices by the octahedron.

Group of rhombohedral calcite crystals of very good size, with defined faces and edges, with interpenetration twins. Slightly pinkish white in colour, matt faces. This specimen stands out for its intense fluorescence and more than notable fluorescence when illuminated with UV-LW light. It comes from the Jaime Murria collection (Barcelona).

Group of interpenetrated pyrite crystals with an exceptional luster. This specimen stands out for its complex crystallography, with cube shapes, triglyphic striations, and vertices rich in probably trapezohedral faces. A piece to enjoy in its study, the kind that I like...

Group of pyrite crystals that show well defined faces of the cube and the octahedron. Very well defined faces and edges, showing triglyphic striations on the faces of the cube and not on the octahedron, as is to be expected. With an exceptional luster. It is accompanied by quartz crystals.

Group of pyrite crystals with cube and dodecahedron faces, with diploid forms, striated faces, certainly complex crystallography, which adds interest to the specimen. Crystals are interpenetrated. The brightness is exceptional, difficult to photograph. It is accompanied by quartz crystals.

Very aesthetic specimen formed by numerous bournonite crystals, excellent luster, sharps and cyclically twinned. They are accompanied by cube octahedral galena crystals with rounded faces and edges and brilliant pyrite. Nice miniature.

In a matrix formed by octahedral pyrite crystals, very bright and faceted, various groups of sphalerite crystals are disposed on which the bournonite cyclic twins stand out. They are accompanied by small quartz crystals and hydrozincite globules. A very aesthetic piece.

A really curious specimen that shows a matrix with well developed crystals of pyrite, partially covered by galena, very bright and with extremely rounded forms, remarkable shape! It is also accompanied by complex crystals of sphalerite. A very aesthetic, unusual and interesting sample.

A floating specimen, all brilliance. It is a rich group of crystals with dominant cube and dodecahedron faces. One of them stands out for its size and the large number of cube, dodecahedron, octahedron, pyritohedron faces. As we said, nice luster and characteristic golden color. It presents small damage without affecting the quality of the sample. An excellent specimen from this Peruvian mine.

These specimens of fluorite are very unusual in the market. Groups of cubic fluorite crystals truncated by octahedron faces, defined, bright and transparent to translucent. There is an aesthetic color zoning, between colorless to slightly greenish with predominant violet tones on the cube faces, a real curiosity. It is accompanied, to add interest if possible, by globular foliaceous aggregates of bright pink cookeite, a member of the chlorite group. Both minerals are very fluorescent under UV-LW light. A good sized display specimen.

A aesthetic good size cluster specimen of pyrite crystals really brilliant, defined faces and edges and with a spectacular luminosity. With some quartz. The picture can not collect all the brightness of the specimen. From a recent find (2016) in this classic Peruvian mine.
