RM1198 Beaverite-(Cu) with azurite and malachite
Bou Bekker, Touissit, Jerada, MoroccoFirst appointment for this Moroccan locality. This lead, iron and rich copper sulfate has been analyzed by SEM-EDS, we will send results to the buyer. Beaverite-(Cu) forms yellow earthy masses formed by lenticular crystals. It is accompanied by fibrous malachite crystals and azurite crystal aggregates.

RM1765 Silver cubic crystals
Aït Ahmane (filon 53), Bou Azzer, Ouarzazate, Drâa-Tafilalet, MoroccoThis 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 (several photos attached).
Size: 10.5 x 5.5 x 3.6 cm.

RM1857 Talmessite with cobaltoan calcite
Agoudal, Bou Azzer, Ouarzazate, Drâa-Tafilalet, MoroccoVery 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.
