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
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 "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.

NDR38XXX: Very clear cubic Fluorite crystals, more isolated than usual, translucent and of a delicate lilac color, more intense towards the edges. They are on a limestone matrix known as 'mountain limestone', typical of the legendary Asturian fluorite.
This specimen has been photographed and published by the magazine ‘Paragénesis’ number 01/2025, page 109
The Josefa-Veneros vein is a classic vein of the central Asturian fluorite district and the most famous of those found there. Mineralization is dominated by Fluorite, associated with a hydrothermal system developed along fractures and veins hosted in Paleozoic carbonate and clastic rocks. Low- to medium-temperature fluid circulation led to the formation of fluorites of great quality and mineralogical interest. The discoveries made there between 1970 and 1974, consisting of Fluorite crystals with well-defined crystal developments and often associated with Calcite, so characteristic of the La Collada area, are still one of the world references for collectible Fluorite specimens, both for their crystallographic richness and their beauty.

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!

We would like to emphasize the geometric color zoning, very intense, with colors that vary from the sky blue, a little greenish, in the external zones to the deepest violet, with a medium lilac zone, and bluish gray in the crystal core.

N90DD9: Crystals of purple Fluorite, with zoned phantoms, good shininess, and small crystals of Fluorite that have grown on the first generation of crystals. On top of that, in the center of the specimen there is an old scalenohedron of Calcite that has been completely replaced by Quartz and which stands upright and aerial on the Fluorite.
The specimen has been reviewed and published in the magazine ‘Bocamina’ on page 60 in number 19, year 2007.

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.

NN6L5: Group of transparent and beveled cubic Fluorite crystals. The main feature of this specimen is the slight curvature of the crystal bevels smoothing the crystal appearance. An interesting miniature.

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.
