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.

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.
