This specimen is not a "museum specimen" but for the collectors of this "territory" it has a very good memories. It is a tourmaline, sometimes dravite other schorl, of the pegmatites of the Collserola range, in the area of Tibidabo-Sant Pere Màrtir, in the city of Barcelona. It is one of those pieces that we can not do without if we like our mineralogy. With old label.

Col. J.M. Manchión (Barcelona). No.164. 03/1985.

A huge size cobaltoan calcite specimen showing concretionary growths with a good and deep purple color. The mineralization is filling fissures of the Triassic conglomerates, which are very visible in this specimen and with a cavity that gives an aesthetic shape.

One side shows a polished section where we can enjoy perfectly banded purple calcite and conglomerate individual clasts. On the other side fracture is totally natural and not polished. Nowadays mine is partially collapsed and restored and it is impossible to get specimens.

Cobaltoan calcite specimen showing carbonate growths with colours between magenta and yellow, typical for this classic Catalan mine. The mineralization is filling fissures of the Triassic conglomerates. Nowadays mine is partially collapsed and restored and it is impossible to get specimens. This sample is from a previous single finding before shaft was filled and some galleries restored.

Nice specimen of cobaltoan calcite with an excellent quality that shows concretionary growths and an incredibly intense color, very deep, with marked zoning. It has been slightly acidulated to obtain a shiny surface that allows to see the color structures without resorting to polishing. A piece full of light, a gem from a mine that exploded precisely to obtain such type of specimens and nowadays totally abandoned and collapsed.

This is one of the old jasper specimens collected by Mr. L. Daunis on the Montjuïc mountain in Barcelona. A place well known by Catalan mineralogists and geologists for the characteristic variety of mineral species that have been collected during centuries. It is a jasper piece with a slightly polished part that allows to enjoy the nobility of this semi-precious stone, the rest presents the original tone. A classic Barcelona sample and label that should not miss in a quality collection.

A group of fluorite crystals those, at first glance, seem just octahedra, but if you take a look carefully you will see complex terminations. Some crystals are isolated increasing its aesthetics. Good transparence and exceptional green color. Acompanied by small quartz crystals.
This specimen belongs to the "old" fluorites from Berta quarry, from an area of ​​sericitized granodiorite. In the fractures, if it was enough space, they grew lining the walls. When quarry worked lower levels fluorite appeared in fresh granite matrix, but mostly without this depth of color. A great speciemen. A classic between classics of our country.

Rich druse of fluorite crystals. This kind of octahedral crystals show a special brilliance due to the multiple growths of small crystals on the faces of the octahedron. This fact gives them a rough surface. Translucent, with good green color and good size. The Berta quarry-mine is in the process of filling and restoration. Not oiled. An old specimen ca. 1985, from Manchion Collection.

Group of fluorite crystals with an intense green color, with transparence, brilliance and sharp edges and faces. Transparence allows us to see an opalescent crystal core on which the crystal has grown with greater transparency. They are disposed isolated on the matrix which gives a superior quality to this specimen. It is accompanied by small rhombohedral calcite crystals and some crystals of pyrite totally pseudomorphed by goethite. Very fluorescent. On a matrix with quartz crystals. Samples with this fine quality are very difficult to find, considering that the quarry is closed to the collectors and the works have been interrupted. From a classic locality.

Group of octahedral crystals of fluorite, nice green color, transparent to translucent and very well defined faces and edges.

A classic between classics of our country. This is a druse of fluorite crystals those, at first glance, seem just octahedra, but if you take a look carefully you will see vertices truncated by cube.

Curious specimen of greenockite of this classic locality of the Catalan mineralogy. Under loupe, aggregates of intense yellow color are observed, with reflections of what could be crystalline faces. This cadmium sulphide is a product of the alteration of rich Cd sphalerite. It is impossible to get specimens today.

These calcite specimens were found in a pocket in the El Americano (Can Sala) mine-quarries, in the Montseny mountains. This big geode was called "Mercedes" due to the curious color zoning that can be observed at the terminal rhombohedrons faces reminiscent of the German automobile company logo.
Crystals appeared partially coated by carbonated iron oxides and sometimes showed a complex prism, sometimes growing on scalenohedral crystals. This calcite shows a intense fluorescence under UV light. These pieces have disappeared from the market.
