The first specimens were found in the mines of Aït-Ahmane between 2014 and 2015. The best ones reached the market around 2017. They are twinned crystals of remarkable perfection for the species, formed by intergrowths of djurleite and chalcocite. No better specimens have been found in the area and probably worldwide.
Although some relatively recent analytical results (see mindat) indicated that they were crystals of djurleite only, others indicated that they were mixtures of both species. Realistically, djurleite and chalcocite often appear together in the same crystal, and one can even transform into the other depending on the physical-chemical conditions present. For this reason I have preferred to preserve the name of both species. Interesting article: Pósfai-Buseck Amer. Min. 1994.

A very faceted tabular crystal of wulfenite. It stands out for its deep blue colour, which is unusual for this species. It belongs from the Bou Skour mine, where crystals of this type have been obtained, but they are usually very small, around a millimetre. This one measures 8 mm...

Group of skutterudite crystals of very good size, exceptional brilliance and forming parallel growths that resemble a rosette. An excellent piece from this classic Moroccan locality that surpasses many of the specimens I have seen.

Aesthetic specimen of good size upholstered by a layer of botryoidal aggregates of chrysocolla, with a pale blue to light blue. On the chrysocolla there are numerous aggregates of acicular malachite crystals, transparent, brilliant, velvety and that stand out on the matrix.

These specimens show us a chalcopyrite matrix partially transformed into irisdecent covellite-bornite and goethite. In the cavities there are numerous aggregates of prismatic malachite crystals, of an intense green, with transparency and brilliance. If we observe them with the magnifying glass we can see that they are faceted crystals. A novelty in the Bleida mines area.

A novelty from the Bleida mines. Groups of malachite crystals, prismatic to needle like, forming velvety aggregates with intense brilliance and color. They are disposed in the cavities of a quartz and dolomite matrix, with cuprite.

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.

Druse of roselite crystals, with good color and defined forms. They are accompanied by pink crystals of cobaltoan calcite.

Rich group of fan-shaped tabular erythrite crystals in parallel growth; very brilliant, of intense color and disposed very aerial on the matrix with quartz crystals. A fine specimen from Bou Azer.

Aesthetic specimen formed by numerous isolated wendwilsonite crystals of good size, very well defined, some of them doubly terminated, with an intense and reddish tone. Some of them partially covered by a whitish patina only on certain faces, selectively. They are disposed on a matrix with calcite and dolomite crystals.

A very aesthetic specimen that shows a vug in the matrix, partially covered by tabular lanceolated crystals of erythrite with a good size. They are disposed very aerial in elegant radial aggregates. Intense color and transparence. A sample of very good quality and that under increase makes us enjoy these arsenates.

Rich group of roselite crystals, with an intense color and good transparence. The analyzes indicate that it does not contain Mg and for the shape of the crystals everything indicates that it is roselite. Accompanied by calcite scalenohedral crystals and globular aggregates of green cobaltaustinite.

Interesting specimen formed by several aggregates of tabular talmessite crystals, standing out on the calcite matrix. In order to confirm the species, we carried out a chemical analysis using SEM-EDS, which confirms the presence of Ca and Mg and the almost absence of Co, consistent with talmessite or wendwilsonite. On the other hand, X-ray diffraction confirms talmessite. Performing this structural (XRD) and compositional analysis (SEM-EDS) allows us to delimit the species. Spheroidal aggregates of slightly curved faces and edges. Color and luster are magnificent for the species and contrast on a base of small slightly pink crystals of calcite (Mn), on matrix. We'll send a the analysis to the buyer.

Vladimirite specimens from Aït Ahmane are among the world's best for the species. It is a rare arsenate that forms aesthetic rosettes of tabular to fibrous crystals, very sharp and colorless. They are accompanied by white aragonite and pink talmessite and erythrite. These specimens were found in the walls near the entrance of the galleries of the 53rd vein of this Moroccan mine. Good sized sample. The SEM-EDS analysis will be sent to the buyer.

Very curious globular aggregates formed by prismatic crystals that vary their composition according to the zone, although the XR diffraction study shows that it is talmessite, without discarding that in some parts of the aggregate a higher cobalt content is observed. These aggregates are disposed on a matrix of cobaltoan calcite, together with manganese oxides. Very interesting.
