On a recent trip to this mining area, we found these new specimens with incredible aesthetics. They were found in a singular cavity, opened in the depths of a 24-meter well, in Coud'a shafts. They have a more than exceptional brilliance, probably due to a last phase of crystallization in which a thin layer of almost transparent vanadinite was deposited. Crystals are very well defined, with staggered axial growths in the prism and with color zoning, more orange than red. Contrasting on a solid rocky matrix. Vanadinites from the Mibladen area are well known worldwide and although we have seen many of them, they never cease to amaze us. Amazing specimens!

On a recent trip to this Moroccan mining area, we found these stalactitic specimens of vanadinite with incredible aesthetics. They were found in a singular cavity, opened in the depths of a 24-meter well, in the Coud'a shafts area. They have a really good brilliance. Crystals show attractive stalactitic growths, also uneven developments in the directions of the prism, very well defined, interpenetrated and with some color zoning. Vanadinite specimens from Mibladen area are well known iworlwide and although we have seen many, they never cease to amaze us. Exceptional specimens.

Classic locality

Galena crystals from the Mibladen mines are not easy to see today, least of all with this definition. They are cubic crystals, with well-marked faces and edges. Some interpenetrated, some very aerial. They are arranged on a matrix with baryte rosettes.

Size: 10 x 4.5 x 4 cm.
Main crystal: 6 mm.
Found in ca. 1980.

Classic locality

Specimen of azurite with a very special, intense color, formed by numerous small crystals, very brilliant. On baryte matrix. They belong to the mine that exploits the immense Marabout vein, located in the north of Sidi Ayed. The coordinates of the mine are 32°53'23''N, 4°38'33''W. Near from Mibladen but in the other side of the mountains.

In this piece, three very interesting magnesium species, two hydroxilcarbonates and one hydroxide coexist. On the one hand we observe some aggregates of foliaceous crystals of dypingite, forming rosettes, white color, although they are colorless. They are accompanied by sheaves of flattened crystals of hydromagnesite. All of them are disposed on a rock matrix with blue to gray brucite. A Catalan piece that is hard to find today, with unusual species and quality.

Size: 6 x 5 x 3.2 cm.

Globular aggregates formed by lamellar crystals of theisite. With a bluish to green color and brilliance. On a dolomite matrix with barite and chalcopyrite. This mineral species is the second citation in Spain. Theisite is a rare copper and zinc arsenate-antimonate that has been described for the first time in this mine in the Catalan Pyrenees. Accompanied by several azurite, transparent, bright, well-defined and some doubly terminated. Analysis results will be sent to the buyer.

Size: 8.6 x 5.5 x 3.5 cm.

Analyzed specimen with report

In this specimen we can observe some groups of tabular wulfenite crystals of intense, very intense orange color, showing defined faces and parallel growth. If anything distinguishes these wulfenite crystals is its vivid color. The brilliance is excellent and in thin areas show transparence. Some of the dominant crystals are disposed very aerial and accompanied by groups of barite crystals. If you observe closely the specimen under the microscope you will see numerous perfect tabular crystals of wulfenite. Very aesthetic specimen.

On a druse of quartz crystals we can enjoy numerous aggregates of hematite crystals with a hexagonal to rounded shape and conical growth, very curious, with brilliance and brown to reddish color. These specimens come from a fortuitous find in an area very close to the well-knoewn town of Sainte-Marie-aux-Mines. An aesthetic rarity.

Superb cerussite specimen from this worldwide classic locality. It shows a cyclic twin, with some more developed crystals, very brilliant, between translucent to transparent, with a very aesthetic pinkish red tone. It presents a second generation of prismatic type cerussite crystals that have grown locally on some faces. Very aerial and with a small matrix. It was acquired in 1975 from Bailey Minerals (Ángel Jesús Talabán García, Segovia 1942-Madrid 2007). A very aesthetic and good size piece.

Very interesting blue-violet to lavender aggregates of johillerite, on matrix, and accompanied by black hematite crystals. Johillerite is a extremelly rare arsenate with sodium, copper and magnesium+zinc: Na(Mg,Zn)3Cu(AsO4)3. Only three localities worldwide: Tsumeb (TL), slags from Genna (Germany) and the Tolbachik volcano in Kamchatka. Johillerite forms a continuous solid-solution system with badalovite and nickenichite. Johillerite samples were obtained from the fumaroles of the North Breach of the great fissure Tolbachik volcano eruption (1975-1976). Cone took 44 days to form.

Aggregate of brown prismatic crystals of this rare niobium and tantalum silicate found in the alkaline pegmatites of the Khibiny Mountains, in this remote area of the Kola Peninsula. It is accompanied by pink aggregates of schizolite, an intermediate member of the pectolite-serandite series, and of lamprophyllite. Identified by Dr. D. Lisitsin.
