The "Collada" and "Josefa-Veneros" veins at La Collada rate among the greatest in Spanish mineralogy. All Spanish collectors dream of having one of the extraordinary specimens in their collection. The specimens have a wide variation in, normally intense, color, modified edges to the crystals, and really very special forms. Although people recently found material in the same region and it is not that distinct from the classic ones, the old timers still have that special something.

In Spain there are two classic localities for quality Fluorite: Berbes and La Collada. At the latter, extraordinary specimens were found when the mine was worked in the 60s and 70s. Their color varied between blue and green, phantoms were frequently present, and the edges of the crystals were often modified. Between 1998 and 1999 with the aid of heavy equipment, they managed to remove the spoil from an area of the La Collada mine and find a number of reasonably sized pockets with good crystals which are violet or deep blue, and often have phantoms. From these finds we were able to present the following specimens.

During December of 2001 in the La Collada area of Asturias, Spain, a series of pockets of Fluorite was found. Physically they was found very close to another old find in the "El Reguerín" area, but luckily the color of these specimens is better than those from the previous find. More intense, with a spectacular color change from sky blue to mauve depending the kind of light. Their luster is better too.
As is quite common in the La Collada area these specimens show naturally modified corners.

At the end of the month of May 2003 in the La Collada mining area they found a superb pocket the size of at least two cars and full of crystallized specimens. This pocket was named "Tres de La Collada" for the name of the area where it was found and it supplied more than 6000 specimens. That seems like a lot of specimens, but as is usual in this kind of find, only a few of this huge total had "collector quality". Well connected with all main Spanish finds, we went there immediately and we made a significant selection of our favorite specimens.
In some cases (the bluer ones) the shape is very similar to the famous old classic La Collada Fluorite, with naturally modified corners. In other cases (the more violet ones) they are completely different from the others found at this locality in the past. The white Quartz matrix in a few specimens completes the fame of the find.
As usual with La Collada classic specimens, the surface of the crystals is not that brilliant, but rather slightly glazed. This is due to a second generation of globular Fluorite (by the way very similar to the new Indian ones) partially covering the surface of the crystals. When viewed with a magnifying glass it is spectacular as it looks like sea waves.
Please note that all the specimens are shown with two kind of lights: fluorescent or day light and bulb light. The color depends so much on which of these two light sources is used that we preferred to display them in the two different lights.

Fluorite from Berbes, Asturias, Spain, one of the classic fluorite localities in Europe at the moment. Given the poor state of the area, the local collectors, who used to find those amazing pockets of fluorite, are finding fewer and fewer good specimens. These are specimens that come from some careful hunting by the locals.

In Berbes, Asturies, one of the most famous pockets was the pocket of 'Coquera del Liso' found in March 1993. One huge rock, which weighed more than 50 tons, had fallen from the cliffs. Inside this rock local collectors found great water clear Fluorite crystals with naturally modified corners, frequently associated with Quartz and Baryte. Fabre Minerals bought the whole pocket. These specimens come from this find.

The Fluorite from the Emilio Mine is known for its incredible transparency and brilliance. When these two aspects come together with the fact that the majority of specimens are colorless they become almost invisible. So one can see the matrix through the crystals as well as other minerals under them or included in them.
Very few perfect specimens are found, as the type of deposit makes collecting them very hard, so any undamaged ones that do come out are highly sought after by both Spanish and other collectors.

For many years under the general locality 'Villabona' many nice lemon yellow Fluorites have appeared on the market, often associated with saddle Dolomite and often quite large Calcite which has interesting crystal form and is white to yellow in color. Less frequently they were associated with blue, white and once in a while yellow Baryte. Pyrite and Marcasite completed the paragenesis.
As so often happens, production has dropped over the last few years and, while the mine is still active, almost no new material has been found.
