The region where the Asturian Fluorites are found is very beautiful, as you can see in this view from Villaviciosa.
Loroñe, a pleasant village next to the Fito hill, which is where the Emilio mine is located.
Views of the village of Berbes, famous across the world for its Fluorites.
A typical 'hórreo' (grain store) in the village of Caravia Alta, which is very close to the Jaimina mine.

Moscona Mine

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.

NA86XD9: This one shows an association of Baryte and Fluorite. The Fluorite is a nice color, is brilliant and has some Dolomite decoration. While the Baryte is small and towards the side of the specimen, it has a nice color, is very aerial, and does not detract from the rest. In the lower part of the specimen there is a contact without crystallized Fluorite, but you do not really notice this as it is hidden by a hump of crystals.

Blue Fluorite from the Moscona Mine

On the 24 December 1999, before its decline, the Moscona Mine, Solís, Asturias, produced, at the 50 meters level, an extremely unusual pocket of two generations of Fluorite. The second generation is bluish Fluorites on a first generation of yellow Fluorite fluorescent on long & short UV, and everything is associated with Calcite, lemon-yellow Baryte and Dolomite.

After all these years without any further similar material being found, we offer some specimens of that unusual Spanish find.

ND96AL9: Fluorite crystals on a Baryte matrix. The Fluorite crystals have polycrystalline growths and the peculiarity of showing two colors, rare in specimens from this deposit, pale violet but clearly yellow around the edges.
The specimen comes from the Miguel David Martínez collection (number 399), whose label we will send to the buyer.
