Specimens from this locality, located in the south of the island of Sardinia, are very rare on the market. This specimen is formed by cavities lined with prismatic barrel-shaped crystals. Intense green to yellowish color. The piece comes from the Manchion collection and was acquired from Dr. Joan Viñals in 1989.

Sold

Sample of metallurgical slag from this classical Greek locality. In the vacuoles we observe these minerals: laurionite, paralaurionite, phosgenite, ecdemite and nealite. It is accompanied by an interesting handwritten label that describes all these species.

This old specimen belongs from the classic Atrevida mine, in the south of Catalonia. It is a botryoidal concretion of aragonite with a slight greenish blue hue. Nowadays is strictly forbiden collect minerals in this Natural Park. From the Manchion collection (Barcelona), with handwritten label of Soler i Pujol old label.

Sold

Specimen from this classic Kosovar mine. A matrix formed by crystals of arsenopyrite, twinned sphalerite, pyrite and some calcite. On them have grown nice aggregates of boulangerite showing a metallic gray fine-acicular crystals, but may have other sulphides of the same group, which are called plumosite. A very brilliant and aesthetic specimen.

Very curious specimen formed by a matrix of baryte, on one side with lenticular crystals sprinkled with vanadinite and on the other with cavities in which aggregates of vanadinite crystals have grown, with color zoning. An old piece with handwritten label.

Sold

Group of cubic fluorite crystals, brilliant, transparent and with a yellow color with zoning, more orange in the core of some of the crystals. Dotted with small beveled cubic crystals of pyrite. The back side is fully upholstered in pyrite.

Sold

An old specimen of smithsonite, with an orange to pink hue, formed by numerous highly faceted crystals, with curved edges and disposed on a matrix with galena, iridescent chalcopyrite and other sulfides. A good sized classic...

Sold

An epidote specimen from an unusual North American locality. It occurs as parallel aggregates of very elongated prismatic to acicular crystals, with terminal faces, green in color and transparent.

Good size smoky quartz crystal. Defined, bright and with "ghost" shapes inside. An old piece from a classic Catalan locality.

Sold

A classic specimen from this Brazilian locality. Various flattened, almost lenticular, siderite crystals with a yellowish green color, on which a group of dolomite crystals stands out. In dolomite we see numerous pseudohexagonal pyrrhotite crystals, some included in the dolomite. We did not observe the presence of cubanite.

Sold

Group of fluorapatite crystals from this famous Portuguese mine. They are accompanied by small lenticular siderite crystals.

This old piece stands out for the size of the crystals and their color. The largest crystal presents the classic fractures, perpendicular to the main axis. The minor, with the terminal face. They are pieces that came out many years ago, around the 70s. This specimen also stands out for the label of Joan Montplet, a well-known mineral seller from Sant Celoni (Catalonia).

Sold

A cluster of "sand calcite" calcite which the locality is well know for. Crystals show a hexagonal form, the main one doubly terminated. From a former Spanish collection.

Sold

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.

Sold

This miniature is a gem, formed by several grossular crystals, with brilliance, very well defined, transparent and with an intense color. Since the mine closed it is difficult to see specimens of this type. From a former Catalan collection.

Fehrite is a recent new species found in Almeria (Spain). Some years ago (2012) we identified this species in the Les Ferreres mine (Camprodon) but unfortunatelly we didn't have enough sample to finish detrmination and structural studies. Recently we found some more samples and the characterization was carried out based on the results obtained from the application of various analytical techniques: SEM-EDS, Raman and X-ray diffraction. Les Ferreres mine is the second locality worldwide for the species. We will send all reports to the buyer.
In this Catalan mine, fehrite appears as elongated elongated tabular to fibrous crystals, with a delicate bluish-green tone, and fibrous terminations. Usually, it is accompanied by devilline (blue) and brochantite (green). It is the magnesium analogue of ktenasite.
