A very aesthetic specimen composed of numerous brilliant, tetrahedral chalcopyrite crystals. They are accompanied by sphalerite crystals. Particularly notable are some partially corroded hexagonal fluorapatite crystals, which fluoresce under UV-OL light. A brilliant specimen for magnification.
A mine in the southern part of the Huarón district, although not operated by the same company that works other Huarón area mines. "Alimon" mine is a misnomer sometimes encountered in the literature. Primarily hydrothermal Pb-Zn-Cu-Ag vein deposits. Located 3 km SSW of the Huarón mine.
A highly aesthetic specimen composed of numerous lustrous, tetrahedral chalcopyrite crystals. They are accompanied by numerous cubic pyrite crystals with striated faces. Also present are black sphalerite crystals. Particularly notable are some partially corroded hexagonal fluorapatite crystals, which fluoresce under UV-OL light. A brilliant specimen for magnification.

Idiomorphic chalcopyrite crystal of considerable size, with defined faces and edges. Some show stepped growth. It is disposed very aerial on a matrix formed by transparent, brilliant, and elongated hyaline quartz crystals. It belongs from the Franco Betta collection (Torino, Italia).
Exceptional quartz specimen, with elongated prisms forming divergent, transparent to translucent aggregates. It has a slightly reddish hue due to the presence of hematite speckles the crystals. It is accompanied by small crystals of pyrite and chalcopyrite. A display specimen from this classic Peruvian locality.
An interesting specimen that shows a matrix covered with clear hyaline quartz crystals. They are accompanied by faceted galena crystals with cube and octahedron faces and very defined edges. They are also accompanied by more complex but also faceted sphalerite. A specimen worth observing with a medium-power magnifying glass.
On a matrix of polymetallic sulfides, partially covered by attractive aggregates of orange realgar crystals, numerous aggregates of hutchinsonite crystals, an interesting thallium-containing sulfosalt, are arranged in sheaves. Many of these specimens are no longer seen on the market. The matrix is serrated on the back.
On a matrix of polymetallic sulfides, partially covered by attractive aggregates of orange realgar crystals, numerous clusters of hutchinsonite crystals, an interesting thallium-containing sulfosalt, are disposed in sheaves; very well defined and lustrous. They are accompanied by tabular baryte crystals. These specimens are no longer found on the market.
A very rich group of octahedral pyrite crystals, with exceptional luster and well defined faces and edges. Accompanied by sphalerite. This mine is the origin of the base for the "Ballon d'Or" award, awarded each year to the world's best football player.
A group of octahedral pyrite crystals, of good size, with exceptional luster and very defined faces and edges. It is accompanied by sphalerite crystals. The base of the "Ballon d'Or," awarded annually to the best player in the world, comes from this mine.

A rich group of cuboctahedral pyrite crystals, with exceptional luster and very defined faces and edges. It is accompanied by sphalerite and quartz. The base of the "Ballon d'Or," awarded annually to the world's best player, comes from this mine. Very good size and remarkable quality.
Cube forms, octahedron and dodecahedron.
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.
This remarkable specimen shows a matrix formed by tabular barite crystals, partially covered with aggregates of tetrahedrite-(Zn) crystals, rich in Ag. With well-defined faces and edges, forming globular aggregates on the barite. A rarity.
Numerous rhodochrosite crystals are disposed on a druse of quartz crystals, defined, transparent to translucent. They present a very remarkable richness of faces, to be enjoyed under magnification, highlighting numerous reflection twins, with dull faces and bright faces alternating by geometry. A very aesthetic curiosity.
A large group of rhodochrosite crystals, with pointed scalenohedron shapes but with striated faces and a very aesthetic pearly luster. The pink-red colour is more intense inside the crystals. It seems that a second generation of rhodochrosite has covered the primary crystals. It is accompanied by crystals of hyaline quartz, together with colourless, well-defined fluorite cubes with opaline faces, except at the vertices, a curious geometry. Aesthetic piece.
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 geocronite-jordanite crystals, with striated pseudohexagonal shapes, very bright and rich in facets. The matrix is mainly composed of geocronite-jordanite, with various cavities where we observe striated crystalline faces.The analyzes show a correlation between geocronite-jordanite, both are isostructural and form series. Crystals analyzed show that the composition moves in the intermediate zone of the series. The geocronite-jordanite crystals are accompanied by sphalerite, galena, associated with transparent crystals of green fluorite.
Parallel growth of hübnerite crystals, of very good size, with evident reddish reflections. With defined terminal faces, translucent on edges and with brilliance. With hyaline quartz crystals. Excellent old piece from this Peruvian mine.
