RM1775   Variscite

Palazuelo de las Cuevas, Zamora, Castilla y León, Spain

Specimen formed by a large group of aggregated nodules of variscite with concentric growths and apple green color. They are enclosed in a matrix with limonite. We can see the concentric structures in the natural fracture. Since its discovery in 1970, the Palazuelo de las Cuevas deposit became the "source" of variscite for the NW of the Iberian peninsula.

Closely observed, it becomes a crystallographic pleasure. From a classic Moroccan mine from where nowadays is not easy to find samples with this quality.

RM1768   Wire Silver and acanthite

Imiter mine, Imiter, Tinghir, Drâa-Tafilalet, Morocco

Very esthetic good size specimen of native silver from Imiter. Interesting for its quality, brightness and because it is not acidified, as is usual in many specimens of this type. It is formed by numerous wire and filiform aggregates of native silver, in a loop, with a slightly bronze color and accompanied by metallic gray acanthite. An excellent piece that shows us the silver of Imiter in its most natural state.

RM1767   Gold with malachite and bornite

Bleida Far West, Bou Azzer, Ouarzazate, Drâa-Tafilalet, Morocco

Novelty obtained on my last trip to Morocco (02/2018). These are brilliant aggregates of gold formed by numerous crystals rich in faces, curved faces and disposed on a matrix of quartz. The SEM-EDS analyzes show that this gold contains a small percentage of silver (<1% weight). They are accompanied by fibrous aggregates of malachite and gray bornite crystals. This specimen stands out for the contrast between the brilliant gold and the green/gray matrix. An exceptional piece. Bleida is a mine located on the eastern rim of the Bou Azzer district.
