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 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. 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.

Group of cubic crystals of fluorite, of good size, with tile growths on the faces. Good brilliance, transparent to translucent. Pinkish-purple color, more blue under LED light. It shows a marked geometric color zoning on the edges. With a baryte book-shape aggregate.

These mines are near the Matagalls peak, in the Montseny massif, and they are also known as Matagalls mines. This sample shows us a matrix with fluorite on which an aesthetic group of book-shaped baryte crystals is disposed. These pieces appeared in the 80-90s of the last century. Nowadays it is very difficult to find good specimens.

Very aerial specimen formed by groups of cubic fluorite crystals. Very well defined faces and edges, with polysynthetic growths and disposed on a matrix with quartz crystals. It is accompanied by a tabular baryte.

Group of interpenetrating fluorite crystals, with an intense coluor that varies according to the type of incident light. From this classic Asturian mining area.

Very good size specimen, formed by numerous very well defined orthoclase crystals. It was in this classic locality in the community of Madrid where, around the 70s, the Daunis-Ruscalleda family, well-known mineral prospectors and collectors from Barcelona, found quite a few very aesthetic specimens of orthoclase/microcline, accompanied by Enrique Kucera. This specimen is one of these ...

Floater aggregate of laminar molybdenite crystals. Very brilliant. A piece of a certain size for this classic Catalan mine. From the Trigo collection (Mataró).

Sold

Good sized specimen with powdered cinnabar aggregates. Intense red color, with an orange point. From this classic mine in Alt Palància (Castelló). For cinnabar locality collectors.

Very good size specimen formed by laminar aggregates of stibnite crystals. The San Antonio mine is located in the area called "Quinola" next to the road BA-5001 between the peoples of Alburquerque and The Codosera. This is an important antimony mine closed in 1986, and it was the largest mine of this metal in Spain and Europe. It belongs from the former Arguijo collection and dates from the 90s.

In this sample we can observe bright and aesthetic aggregates of lanceolated foliaceous hydromagnesite crystals, forming rosettes, of an intense white color, although they are colorless. All of them are arranged on a rock matrix. A Catalan piece that is difficult to find today, with rare species and with quality. Collected by Joan Astor in march, 1976.

Sold

A very good size specimen formed by numerous lanceolated baryte crystals, with very good definition of faces and edges. Between transparent to translucent and with a yellowish tone with zoning. They are disposed very aerial on the matrix, with crystals of calcite and fluorite with honey tones. Fluorite is active under LW-UV light. An exceptional specimen for this classic Asturian mine.

Group of doubly terminated quartz crystals, with developed prisms and defined terminal faces, translucent. With interesting parallel growths. These specimens were collected in this A Coruña quarry that exploits quartz, one of the main mines in the world due to the quality and quantity of its reserves. The mine was discovered in 1968 by three Galicians who gave their name (from their surnames SEñarís, RAma and BALboa) to the concession and who found it while exploring these mountains in the Pico Sacro area in search of "seixo" (from the Galician: hard white rock) of good quality.

Aggregates of brilliant and transparent baryte crystals, with a slightly yellow tone. They are accompanied by small crystals of sphalerite, with complex forms, and galena. It comes 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.

Specimen formed by aggregates of radial aragonite crystals, with very aesthetic bands of delicate blue color. This old specimen (1980s) is labeled as collected in Peñamellera, Asturies (Spain). Other specimens like this and from the same years where labelled as collected in this Asturian locality. A curiosity from the former Joan Astor collection (Barcelona). With original labelled box.

Group of analcime crystals, faceted and translucent to transparent. They are disposed on a rocky matrix partially covered by small prismatic prehnite crystals. From a currently restored quarry.

This specimen of goethite after pyrite from Pedrera Berta (El Papiol, Barcelona) shows several cubic crystals completely transformed into goethite and limonite. Very brilliant and with fluorite on matrix. A classic of this mine, nowadays not easy to find. It belongs to the Joan Astor collection (Barcelona), with a handwritten and typewritten label.

Sold

On this classic matrix from Pedrera Berta (quarry), with quartz, fluorite, pyrolusite... we can observe some cavities in which some small but brilliant rhombohedral smithsonite crystals stand out, with a golden color. Viewed under magnification they are really aesthetic to take a "microphoto". They are accompanied by malachite aggregates. Collected by the well-known Catalan mineral collector Manuel Moreno "Manolo" and from the Joan Astor collection, with labels.

Probably čechite specimens from the "Rasa de l'Alzina" open pit works could be considered between the best crystals for the species worldwide. They are brilliant, black color and show a tabular shape defined by different order orthorhombic prisms and developed pinacoidal faces. They are disposed on a fluorite matrix. This finding is close to the Maria Magdalena mine, near of the beautiful town of Ulldemolins (Tarragona, Catalonia).
SEM-EDS and EPMA analysis show that, in some cases, on the čechite crystal surface we found copper content, but inside the crystal is near to pure  PbFe2+(VO4)(OH), with minor Zn(II). In most specimens from other localities the presence of manganese is important, but these specimens are Mn free.
