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.

Size: 6.4 x 4.2 x 3.6 cm.

Very esthetic specimen of elbaite (var. rubellite) showing an elongated prism with striations, defined terminal faces, good brilliance, translucent and the characteristic color, slightly lighter in the upper part.

Wulfenite specimens like the one we present are very unusual for this locality and appeared many years ago. On a matrix with dolomite, galena and baryte there are numerous crystals of intense orange color, with dipyramid faces truncated by the pinacoids. Some appear as isolated crystals and mostly in parallel growth. This specimen is from the Peter Seroka collection and previously belonged to the Marcus Lueg collection.

Size: 7.9 x 7.2 x 4.8 cm.
Main crystal: 1.1 cm.

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.

Main crystal: 2 cm.

These specimens are formed by numerous prismatic crystals of albite, very well defined and interpenetrated. They are accompanied by acicular crystals of actinolite and epidote, and octahedral magnetite. A piece of good size and quality. They were sold as orthoclase but a recent XRD analysis I have done indicates that it is albite (2/15/2024). Maybe more interesting.

These prehnite specimens are a novelty from the Mineralexpo Barcelona-Sants 2022 mineral show. They show rich groups formed by sheaf aggregates of crystals, very brilliant, translucent and with a very uniform green color. Sometimes they are accompanied by small acicular crystals of actinolite. They belong from a Moroccan locality near Boulemane.

These baryte crystals are very different from the usual ones that we can see coming from this Moroccan locality and even from other deposits famous for baryte. These are prisms of different orders, the predominant third order, truncated by the second order. We observe that a white geometric growth has formed and only affects certain faces of the rhombic prisms. This zoning is unusual for the species. The crystals are transparent and brilliant.
