Group of fine prismatic crystals of calcite of hexagonal shape, with colour zoning and small recrystallizations of the same calcite in some areas of the piece. The crystals are on a fluorite matrix with quartz and small pyrite crystals. Both calcite (red-pink) and fluorite fluoresce under UV light.

Anglesite specimens from this classic Moroccan mine are quite difficult to find. In this piece we can see numerous lanceolated prismatic crystals of this lead sulphate, very brilliant, with well defined faces and edges, transparent and showing the natural yellow colour characteristic of this species and mine. They are disposed filling cavities in a galena matrix.

Cluster of aragonite crystals, very bright and defined. They are known in the area as "sputnik stones" (sic) because of their appearance. They present a color zoning on the surface, between gray and brown. They are floating. A Moroccan curiosity.

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.

Group of tabular crystals of calcite of hexagonal shape, with color zoning and small recrystallizations of the same calcite in some areas of the piece. Crystals are on a matrix with fluorite, quartz and small pyrite crystals. It shows a intense reddish tone under UV light. Aesthetic specimen from this classic Moroccan locality.

Espécimen muy rico formado por numerosos agregados de cristales aciculares blancos (transparentes) de picrofarmacolita, acompañados de eritrita rosada rica en Mg (hörnesita), junto con farmacolita y sainfeldita. En matriz. Estos ejemplares fueron extraídos de la mina Bou Azer en febrero de 2018. Son muy estéticos bajo aumento, con buen tamaño para colección.

A rich group of epidote crystals of a very good size and an intense green, almost black color. The crystals show very well defined prism faces of different orders. This crystal shape is quite unusual for this Moroccan 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.

Intense orange color and good luster chabazite-Ca well defined crystals. With matrix on its back side.

Vesuvianite crystal, with defined faces, doubly terminated, green to dark brown in color. It is labeled as coming from the Imilchil area. Good size and aesthetics.

White elongated crystals of pearly luster in parallel growths implanted on groups of crystals of malachite with a silky luster and a very deep and uniform color. From a find ca. 2010 in Bou Beker where this association had not been found before.

Very aesthetic specimen formed by several aggregates of vanadinite crystals, labeled as arsenical endlichite. Very well defined hexagonal prisms, beige in color, peppered with tiny but brilliant and well defined crystals of descloizite-mottramite, with dark honey tones. The descloizite-mottramite forms globules but also partially covers vanadinite crystals, especially on the pinacoidal faces and forming "half moons", a curiosity. These specimens from this Moroccan mine are not common.

Specimen very rich in prismatic epidote crystals, well defined, with an intense green color, transparent to translucent. These pieces came out in the late 1990s and are different from the usual ones for the locality. It was acquired by Peter Seroka from G. Gautier at the Munich Show in 2002.

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.
