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.

This is a specimen of tabular barite crystals, colorless to yellowish tones and very good transparence. It belongs from the Mines d'Osor, currently closed and from which it is impossible to obtain these specimens. The mine closed in 1979 and had eleven levels, with a 290 meter deep shaft. You can still see the ruins of the old facilities and the well from which sphalerite, galena and fluorite were extracted and treated.

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 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.

Various aggregates of quartz crystals, some doubly terminated, with transparence and brilliance, partially dotted with small reddish globules of hematite, which partially cover a matrix with bluish crystals of fluorite. These specimens that we offer were collected at the beginning of the 70s. The mines were exploited until the mid-90s and have been partially restored.

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.

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.

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

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.
