This specimen is totally different from those that we usually see in the market of this Moroccan locality. The matrix is a group of quartz crystals, with a soft amethyst tone, and partially covered with chalcedony, in tiny, shiny crystals. On this matrix there is a large group of goethite crystals, lanceolate, dark brown in color and also covered with chalcedony. But millimeter quartz crystals stand out above them, most of them doubly terminated. I had never seen specimens that looked like this. Very interesting.

Classic locality

Cerussite specimens from the Mibladen area are usually yellowish. In this specimen from the Seroka collection we can see very brilliant and transparent crystals and the largest ones are cyclically twinned. This type of specimen is not common in this area. It fluoresces weakly yellow under UV light.

Size: 5.7 x 3.9 x 3.9 cm.
Main crystal: 11 mm.

Prismatic crystals of nepheline, associated with a matrix with black schorlomite (garnet group). Although nepheline is a fairly common rock-forming mineral in silica-poor igneous rocks, such as nephelitic syenites, well-formed crystals of this species are rare.

Col. Peter Seroka (#4875).

Very esthetic specimen of celestine from Morocco. It shows us a large group of prismatic crystals of this strontium sulphate, very well defined and faceted, and with an excellent transparence that allows us to see a soft bluish color. They are disposed on a compact matrix. This locality is northeast of Imilchil town.

Size: 10.2 x 9.5 x 6.8 cm.
Main crystal: 2 cm.

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.

Divergent aggregates of good sized acicular to prismatic goethite crystals. They are accompanied by black globular aggregates that, once analyzed, have turned out to be a first generation of goethite. It is accompanied by small aggregates of green conichalcite crusts, also analyzed. The specimen shows a fissure that has been consolidated, without affecting its stability and aesthetics.

Classic locality

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.

Col. Joan Astor (Barcelona). cv.

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.

Size: 8 x 6.5 x 4.9 cm.
Main crystal: 5.4 cm.

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.
