Group of chalcopyrite crystals, bright, interpenetrated, with well defined edges. On the faces of the crystals we can see small aggregates of crystals, probably tetrahedrite. They are accompanied by sphalerite crystals on matrix. An old piece, from the time of those that are preserved in the Freiberg Mining School Museum.

We have labeled this specimen as fluorite, because it highlights a group of crystals of this species, transparent to translucent, with complex facets of the dodecahedron, with faces with polysynthetic growths. They are disposed in a vug of bright rhodo crystals and intense pink. A second generation of rhodo forms globules of honey tone. A very curious and aesthetic Mina Uchucchacuapiece.

Group of bournonite prismatic crystals, with striated faces by the cyclic twin; interesting acute terminal faces, good brilliance and complete crystals. They are accompanied by bright aggregates of acicular boulangerite and sharp pyrite crystals. They are accompanied by lenticular crystals of possible magnesite or dolomite. A sample purchased by Sr. Manchion from Dr. Joan Viñals, in the 80s. A different piece from this Peruvian locality.

Very large group of rhodochrosite crystals, very bright, transparent and richly faceted. They show interpenetrated figures of the rhombohedron and the escalenohedron. The pink color is very uniform and intense. They are disposed forming aggregates or as isolated individuals, on a matrix with kutnohorite. A old piece belonging of the first specimens those arrived from these Peruvian mines.

Size: 6.0 x 5.2 x 3.7 cm.
Main crystal: 5 x 3 mm.

Very rich specimen formed by several tetrahedrite crystals, sharp, brilliant, with golden facets due to chalcopyrite. They show forms of the tetrahedron and the cube, together with more complex ones. They are disposed very aesthetically on a matrix covered with quartz crystals and peppered by globular orange siderite. A very esthetic specimen, for lovers of crystallography and sulfides. Analysis show a silver content.

Size: 8.3 x 6.0 x2.7 cm.
Main crystal: 10 x 8 mm.

Analyzed specimen with report

Epidote crystal of a really good size (also for this locality), very sharp and with parallel growths, developed prism, striated. Near doubly terminated. The terminal faces are well defined by various pinacoids. The brightness is excellent and the intense green color can be observed when the light strikes the crystals. Of a little represented locality in the collections.

A very interesting cluster of sharp epidote crystals showing a developed striated prism and parallel growth. Terminal faces are defined by various pinacoids. The brilliance is excellent and the deep green color, near black in thick crystals, could be perfectly observed when light crosses through them. From a Peruvian locality not well represented in collections. Take a look in Mineralogical Record Tom's Online.
