In a building works in Cal Gairal street, in the Rocabruna village (Bruguers, Gavà), a few specimens of intense green variscite were found forming veins in grey slates. Unfortunately when we were able to access these works, the exact place where these specimens were extracted from had already been filled and covered with concrete. Variscite had not been found in the Bruguers area for many decades, let alone with this quality. X-ray diffraction results indicated the presence of crandallite. We recommend the recently published book: "Mines i minerals de la serra de les Ferreres. Les mines de Rocabruna, Bruguers, Gavà" (Catalan language).

Group of very well defined fluorite crystals, between transparent and translucent, and with a yellowish-green color characteristic of this mine. Some have color zoning. They are accompanied by small crystals and hyaline quartz. These specimens that we offer were collected in the early 70s.

A Catalan new found. Group of amethyst quartz crystals in parallel growth, transparent to translucent. On quartz matrix. The area is known for historical finds of smoky quartz crystals, not so much amethyst quartz.

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.

Baryte crystals from this quarry are a classic of Catalan mineralogy. They appear in the fissures of the slates, usually covered by iron oxydes. In this specimen we can see various groups of prismatic crystals, brilliant and transparent, rich in faces. Among them, a larger one stands out in which we can see the faces of orthorhombic prisms of various orders truncated by pinacoidal faces. Nowadays it is very difficult to find specimens in this quarry and even less with the quality we offer.

Fluorite specimens from Sant Marçal mines usually appear as aggregates of cubic crystals, defined, sometimes sprinkled or partially covered by quartz crystals. Yellow to greenish tones are the usual ones. Specimens with violet to bluish colors (depending on the type of incident light) are much less frequent and highly appreciated by collectors. These specimens we offer were collected at the beginning of the 70s. Some small nick, very common in these specimens, without affecting the quality. In this specimen we can observe cubic crystals with this bluish to greenish tone, translucent and disposed on a characteristic ochy "pegmatite" matrix. They are partially covered and on with small but brilliant quartz crystals.

The Matagalls fluorite mines are located in the Montseny massif. They are well known for fluorite, but also for quartz crystals of the amethyst variety like ones shown in this specimen. Numerous amethyst crystals are disposed on a matrix upholstered by yellowish-green fluorite, partially covered by small very brilliant calcite crystals.

This specimen of fluorite from the Berta quarry shows us groups of crystals but also isolated crystals. The matrix is "old" red granodiorite and is lined by tiny, almost colorless fluorite octahedrons. If there is something to be highlighted about this piece, it is that the octahedral fluorite crystals show the faces of the rhombododecahedron, the cube and the tetrakishexahedron at the vertices.

Group of octahedral fluorite crystals, transparent and showing an intense green color. They are accompanied by small calcite crystals, very faceted, transparent and brilliant. Both fluorite and calcite fluoresce under long-wave ultraviolet light. This type of gray granite matrix is classic for the most modern specimens and comes from the lower levels of the Berta quarry.

Group of octahedral fluorite crystals, translucent to transparent. They show defined faces and edges and an intense green color. They are accompanied by small quartz and pyrite crystals peppering some of the octahedron faces. This type of gray granite matrix is classic for the most modern specimens and comes from the lower levels of the Berta quarry.

The Sant Marçal mines (also known as Matagalls mines) are located in the Montseny massif, on the eastern slope of the Matagalls peak (1,700 m). Mining works were carried out at 1,250 to 1,350 m of altitude. The municipality corresponds to Viladrau. Mining in this type of deposits in this area and surrounding areas had been focused on the extraction of minerals of Pb, Zn, F and Ba. Together with the Osor and Tagamanent deposits, the Rigròs main vein from Sant Marçal mines is one of the most important in terms of fluorite extraction. Although there are other less thin mineralized veins in the area. These veins are embedded in granodiorite rock, which locally present metric dikes with a pegmatite texture. the granodiorites are usually altered to "sauló" (coarse-grained sand with micas, clays and quartz grains) and in some specimens it forms part of the matrix. The paragenesis of these veins: fluorite, baryte, galena, pyrite, chalcopyrite and quartz (often amethyst variety). They were mined until the mid-90s and have been partially restored. Currently this area belongs to the Montseny Natural Park, so the collection of specimens is totally prohibited.

Very interesting combo formed by a tinticite nodule with some calcioferrite small aggregate. Calcioferrite is showing olive green globular aggregates, with radiated crystals, included in tinticite matrix. These specimens have been analyzed by SEM-EDS and XRD and we will send all details to the buyer. From this classic Catalan mine.

In this specimen we can see a group of bluish fluorite crystals partially covered by a druse of minute but very bright quartz crystals.

Very good sized specimen of fluorite from this classic Catalan quarry. On the "old" matrix of orange granodiorite there are various groups of crystals, some of them isolated, with octahedral shapes. They have a semi-matte luster and a uniform green color. Very fluorescent under LW-UV light. Specimens of fluorite from this quarry are highly prized by collectors.

Baryte specimens from this classic Catalan mine are rare on the market. In this piece we can see a large group of interpenetrated crystals, highlighting some of them with clearly visible faces. They have a slightly yellowish color and are translucent. This specimen comes from the Joan Astor collection.

Near the coast of the Catalan city of Barcelona is emplaced this historical and geologically very interesting promontory such as the Montjuïc mountain. The sample we propose is a xylopal (opal wood) in which we can observe structures of the original wood. These specimens are already as historic as the mountain from which they belong...

The Sant Fost willemite appears in small crystals with a pseudohexagonal prismatic habit (twinned), with striated faces. All of them are sub-millimetric in size and form druses of crystals with a resinous or adamantine luster, with colors ranging from dark brown to honey-yellow, or they may appear colorless and transparent. In Sant Fost the willemite appears associated to a sphalerite vein together with silicates (quartz and clays), calcite, fluorite, and baryte. Willemite is fluorescent under SW-UV light. Very unusual locality for the species.
