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.

Highly aesthetic botryoidal malachite aggregates completely covered by a layer of slightly greenish-blue chrysocolla. We can see the malachite, with concentric growths, in some fractures. The beauty of these specimens makes them worthy of the finest collection and display case.

In this specimen, we can see numerous tabular ferberite crystals with a very unusual orientated parallel growth. Very lustrous and intensely black in color, they are arranged on a matrix of clear quartz crystals. This specimen comes from the Nicolau collection (Barcelona) and was acquired from Dr. Joan Viñals.

Group of andradite crystals, which show us very well defined faces of the dodecahedron truncated at the edges by those of the trapezohedron. It has an intense brown color and a more marked shine on the trapezohedron faces. Specimen from this classic Russian town that is rare today.

Amazing aggregate of prismatic pyromorphite crystals on a baryte matrix. Many of the crystals are doubly terminated and have a good size. They shows slightly curved faces and edges, are a very brilliant olive-green color on the prism with intense yellow tips. On a baryte matrix with galena (not in quartz as the label indicates). This shape is highly appreciated by collectors. This classic French specimen was purchased by a collector to Fabre Minerals.

In this specimen, we can observe several hexagonal pyrrhotite crystals that have been completely replaced by pyrite. The luster is very good, and they stand out in a matrix formed by numerous quartz crystals. With black sphalerite. A very interesting and aesthetic pseudomorphosis.

In this specimen, we can observe numerous rosette-shaped aggregates formed by lenticular rhodochrosite crystals, with a faint pink hue that contrasts with a matrix composed of numerous quartz and calcite crystals, some of them flattened rhombohedrons. It is accompanied by several faceted crystals of brilliant chalcopyrite. A highly aesthetic specimen from this classic Kosovo mine.

The anatase crystals from this Norwegian locality are a classic of world mineralogy. They are notable for their size. In this specimen, we see a crystal formed by a tetragonal bipyramid truncated at the vertices by pinacoids. Growth contacts and some small chips can be observed, but they do not detract from the quality of the specimen. It is disopsed very aerial on a small quartz matrix.

A specimen composed of several good-sized microcline crystals with well-defined faces and edges, accompanied by white albite crystals. A group of smoky quartz crystals with good luster and transparency stands out at the top. This specimen comes from the collection of Peter Seroka (Potsdam, 1942 - L'Escala, 2020), a well-known German collector residing in Catalonia and a lover of feldspars.

The Yinnietharra dravite crystals are a classic of world mineralogy. Nowadays they are not common and can only be obtained from old collections that were lucky enough to be formed when the mines were worked. This specimen shows us a good group of doubly terminated dravite crystals, with very defined faces and edges, shiny and with the characteristic toasted honey color. They are accompanied by muscovite. An AMAZING specimen!!!
