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.

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.

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.

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.

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.
