RM3233 Silver and acanthite
Balcoll mine, Pozo 2 (shaft 2), Falset, Tarragona, Catalunya, SpainIn this specimen we can enjoy several groups of wire silver, with showy wire to skeletal growths and metallic luster. Accompanied by black acanthite crystal aggregates. From a classic locality for the Catalan and Spanish mineralogy. A good chance to represent this locality in your collection. Nowadays it is very difficult find specimens, only from old collections...

RM3139 Fluorite and quartz
Sant Marçal (Matagalls) mines, Sant Marçal, Massís del Montseny, Viladrau, Girona, Catalunya, SpainFluorite 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 or green 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. 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 with small but brilliant quartz crystals.
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. 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.

RM3117 Variscite and crandallite, in matrix
Cal Gairal street outcrops, Bruguers, Gavà, Barcelona, Catalunya, SpainIn 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).

RM3008 Fehrite and devilline
Les Ferreres mine, Rocabruna, Camprodon, Girona, Catalunya, SpainFehrite 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.
Size: 2.3 x 1.1 x 1 cm.
