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 cube octahedral pyrite crystals forming a very aesthetic and brilliant aggregate.

Size: 4.8 x 3.9 x 3.2 cm.
Main crystal: 19 mm.

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.

Rich group of octahedral pyrite crystals, with an exceptional luster. A good-sized, very aesthetic specimen, from this classic Peruvian mine.

Size: 12 x 8.2 x 5 cm.
Main crystal: 22 mm.
Found in 2023.

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.

Size: 4.5 x 3.6 x 2.4 cm.
Main crystal: 8 mm.
Found in 2019.

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.

Size: 5.2 x 3.8 x 3.2 cm.
Main crystal: 6 mm.
Found in 2019.

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.

Size: 6.2 x 6.0 x 4.4 cm.

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.

Size: 6.7 x 5.5 x 3.8 cm.
Main crystal: 2.8 x 2.8 cm.

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.
