Good size epidote crystal, dark olive green in colour, very bright, with defined terminations, striking lighter green reflections and many flashes of greenish-yellow internal fire. Excellent specimen of Peruvian epidote.
Group of rhodochrosite crystals with a uniform pink color, with well-defined rhombohedron echeloned and scalenohedron forms. Good gemmy transparence. They are accompanied by other smaller rhodo crystals. On a solid matrix with quartz crystals with inclusions and manganese oxides.

An old specimen of this Peruvian mine that shows a large group of cubic galena crystals, interpenetrated, with its characteristic gray tone. They have stepped growths on the faces and some natural cavities, which give them a differentiated appearance.
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.

Group of rhodochrosite crystals that stand out for their color, with well-defined scalenohedron shapes and good transparence. Accompanied by other smaller rhodo crystals. On a matrix with manganese oxides, hyaline quartz crystals and some colorless fluorite.

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.
Amazing specimen of clinoatacmite that shows several groups of pseudohexagonal crystals of really good size. With an intense and deep green color, brilliant and with some transparence, some twinned. They are disposed as isolated groups that stand out on a matrix of hyaline quartz crystals, with blue-green tones due to the chrysocolla and malachite they're are covering. An great an exceptional piece.
Aesthetic specimen that shows several clinoatacamite crystals, with a pseudorhombohedral shape, with an intense green color, brilliance and transparence, some twinned. They are disposed as isolated individuals those stand on a matrix of brilliant quartz crystals, with blue tones due to the chrysocolla and green due to the malachite. A remarkable piece from this Peruvian mine (enjoy pictures).
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.
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.
Very visible quartz Japan twin law (84°33'), formed by two well developed crystals. Transparence, perfection and with very interesting reddish acicular inclusions of indeterminate species (hübnerite?). From a classic locality very aesthetic piece.
Very rich group of sharp clinoatacamite crystals, many of them isolated, very well defined faces and edges, interpenetrated, with pseudohexagonal and octahedral forms. Very brilliant and with some transparence. They are disposed on a matrix formed by brilliant quartz covering aggregates of deep green malachite crystals and chrysocolla. Peppered with scalenohedral crystals of calcite. A very aesthetic and interesting specimen of good size. I like Peruvian clinotacamite...
Very curious specimen formed by a sharp rossette formed by clinoatacamite crystals, with an intense green color, with pseudohexagonal forms. They are disposed on a brilliant matrix covered by quartz crystals and chrysocolla.
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 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.
A huge size rhodochrosite crystal with an intense red color and well defined scalenohedral forms. Good color and transparence. On a solid rocky matrix with hyaline quartz and cubic fluorite crystals (fluorescent). A good specimen hard to find...
