Druse of quartz crystals, milky to hyaline at the tips, with a certain reddish hue. It comes from a Moroccan locality unknown in collections, located in the Boulemane area, north of Aouli. Formed in volcanic rocks.
Hemispherical aggregate of smithsonite crystals, of good size, luster and with a very curious orange-brown color. On the label of the A. Trigo (Mataró) collection it indicates that he bought this specimen from a Moroccan dealer (1989) as "tornuisite", a term for which we have not found references, unless it was wrongly confused with "tarnowizite". Touissit specimens of globular smithsonite are known but rare.
Group of cubic fluorite crystals, with good brilliance, transparence and a very characteristic green color. From this classic Moroccan mines. With the label of the former collection Trigo (Mataró).
These specimens of manganite partially replaced pyrolusite, come from a locality not yet described in the mineralogical bibliography. This deposit is located in the province of Boulemane, in the Fez-Meknés region, about ten kilometers from the well-known Aouli mines. It is a formation very similar to that of Imini (near Ouarzazate). These manganese deposits, both in Imini and in the Boulemane area, were formed in a karst system. Associated with shallow marine dolomites of the Cretaceous age and that currently form sub-horizontal mantles cutted by erosion, overlaping areas of volcanic rocks. Manganese minerals are found in dolomite breccia and ferruginous clays. We have carried out X-ray diffraction studies showing us the presence of both species: manganite and pyrolusite.

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.

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.
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 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.
Good-sized azurite crystal from this classic Moroccan mine. It shows very defined and bright faces and edges, with an intense blue color. It presents a small nick in the upper part but almost invisible. Good specimen indeed.
Good sized cerussite crystal, with cyclic twinning, complete, and polysynthetic growths. Good color and defined faces, disposed very aerially on a matrix with baryte crystals. A very aesthetic Moroccan classic. With handwritten label.
Group of quartz crystals, with defined rhombohedron forms and parallel growth (faden). Excellent brilliance and transparence. These are specimens from a Moroccan mine that is poorly represented in collections.
Group of quartz crystals, with defined rhombohedron forms and some with more development faces, poorly developed prisms. Excellent brilliance and transparence. These are specimens from a Moroccan mine that is poorly represented in collections.
