Specimen formed by two cerussite crystals of a more than considerable size. They show the cyclic twin, with staggered growths. At the vertex of the largest crystal we can see the twin clearly. They are not shiny and have a rough crystalline surface on the back, but they are exceptional for their size and crystallography. They are disposed on a small baryte matrix.

RM2603   Silver

Aït Ahmane (filon 53), Agdz Cercle, Zagora, Drâa-Tafilalet, Morocco

This specimen stands out for showing arborescent growths of very well defined silver cubic crystals. In addition, the piece comes from a Moroccan mine from which few samples of this type and quality have been collected. To add more importance to the piece, it must be said that the calcite has been partially removed by mechanical procedures, without acids that could cause the silver to blacken. Well defined, extremely brilliant and isolated silver crystals are not very common, usually appear deformed or in complex growths. An excellent and good sized specimen.

RM2437   Pyrolusite replacing manganite

Boulemane area, Fès-Meknès, Morocco

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.

Main crystal: 3 cm.

RM2284   Vanadinite on matrix

Coud'a 24m↓, Mibladen, Midelt, Drâa-Tafilalet, Morocco

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!


Size: 10 x 8.5 x 7 cm.
Main crystal: 1.2 cm.
