JFD241AQ1: A good example of what the Reguerín I pocket yielded. I liked its architecture, and that the Fluorite was mounted on Quartz with its characteristic perimorphs of Calcite, which have growth phantoms too and, in general, has more “life” than most other pieces from this pocket, whose specimens generally had larger cubes, but whose overall look was more “dull” than the appearance of this piece, which I always found to be very cheerful.

NFR66AQ1: A novelty for Spanish mineralogy (see: La extraordinaria paragénesis de minerales de mercurio de Usagre)
Group of Eglestonite crystals -a mineral species produced by the alteration of other mercury minerals - with the dominant forms of the octahedron, on matrix, of a honey color, translucent, and completely filling a vug, as well as being dispersed in the rest of the piece. They are accompanied by Calomel crystals with an adamantine luster, and small Mercury droplets that are sustained thanks to their high surface tension.
Both of the mercury halide species have been analyzed and we will send a copy of the analysis to the buyer.
These minerals are photosensitive, blackening easily in sunlight and even under the light of a lamp, so we recommend keeping them in the dark.

Both of the mercury halide species have been analyzed and we will send a copy of the analysis to the buyer.
These minerals are photosensitive, blackening easily in sunlight and even under the light of a lamp, so we recommend keeping them in the dark.

TFE91AQ1: Druse of very sharp Fluorite crystals, transparent, with good luster and an intense deep violet color. With selective coatings of Calcite and even a scalenohedral crystal that is of large size for the locality, where Calcite is normally rare. Also with parallel growths, which includes small second generation Fluorite crystals. The Calcite crystal exhibits some small cleavage, forgivable due to its uncommon size.
This very unusual specimen was in the collection of Tomás Cerezo in Alicante.
Los Cobayos Quarry (La Paredona), Berbes mining area, Los Cobayos, Berbes, Ribadesella, Comarca Oriente, Principality of Asturias (Asturias)  Spain (±1990)

Subsequent recrystallization of the Fluorite has created crystals with balanced cube and tetrahexahedron forms, transparent, with good luster and a uniform light blue color.
We must add that the locality produced only very few specimens, but which were very characteristic with the tetrahexahedron and the transparency and brilliance of the Fluorite crystals.
