This page provides a selection of the specimens that have passed through the Fabre Minerals website and, due to their quality,
rarity, or significance as specimens from interesting locations, have been preserved as reference specimens in #MVM
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.

From when mining ended at La Collada until 1998 almost no new specimens were found in the area. That said there were a few finds, such as the large April 1994 pocket called 'Geoda del Reguerín' which was found near the La Viesca area. The pocket was filled with water, but from beneath the water a large number of specimens emerged, with light sky blue crystals of Fluorite that have pale violet phantoms. While the crystals are not that large they are very transparent, and almost always on Quartz matrix. We bought the majority of this find and have some of them below.

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.

N8DD9: More transparent and brilliant than most other specimens from La Collada, and, as it lacks the typical modification to the edges, it looks more like one from Berbes – but it is from La Collada. Very nice as well!

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.

NE58G8: Color and luster are, maybe, less intense than usual but compensated by the esthetical aspect of the piece, aerial on a fine matrix of Quartz, and the shape of the faces, that are clear on their beveled edges.

NM61D9: Let’s see: some scalenohedrons of Calcite once existed in the pocket. They are now long gone and all that remains is the form of the faces of the old Calcite crystals that have been preserved by the coating of Quartz that formed on them. It is a floater with a very clean appearance and great originality. It is the most spectacular of the specimens of this type that came out of this find.
The specimen has been reviewed and published in the magazine ‘Bocamina’ on page 62 in number 19, year 2007.

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.

NZ47D1: Extremely large, this showy specimen is the best of the find in this size. I think that the photo says everything, but let me tell you that the form it is just wonderful, the color is very intense, and the whole specimen very spectacular when you have it in front of you!.

NT86T0: Group of cubic crystals with intense luster and a very deep color, violet with bluish shades, and geometrical color zoning on the bevels. They are on a group of white scalenohedral crystals of Calcite. The sample is from material compiled for years by Fernando Brugos, former owner of the La Viesca claim. This material has been accurately documented, regarding the different pockets as well as the dates of the finds.

NG46F7: Calcite is not so common in this Quarry. In this case we have a quite large, rounded crystal of Calcite on the typical matrix of Fluorite and Quartz, although in this case the Fluorite is colorless. Curiously the Calcite is intensely yellow-orange near the rear, almost certainly due to the presence of oxides that were in the iron rich fluids from which it formed.
