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.

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.

Hambergite is a rare mineral species, a beryllium hydroxyborate, which occurs in the tourmaline pegmatites of Anjanabonoina. This sample shows us a group of crystals of exceptional size and quality, flattened and with well-defined terminations. Transparent to translucent, with brilliance. This mineral is usually found as single crystals, rarely on matrix, and less with this size. A museum piece.

Size: 7.2 x 5.2 x 4 cm.
Main crystal: 3.7 cm.

Exceptional specimen of kolwezite, which occurs as globular aggregates of olive-green crystals, partially covered by a yellowish earthy patina. They are disposed on a matrix of pink crystals of cobaltoan calcite. An exceptional sample for the species. We have analyzed it to check the content of Co. The average of various analyzes indicates a Co: Cu ratio of 1: 2.3-2.6, consistent with some results from other specimens with 1: 2 ratios. Various black aggregates appear in the sample, sometimes partially covering kolwezite, which corresponds to heterogenite. Also with small malachite crystals.

Size: 9.8 x 7.5 x 6.2 cm.

A huge size crystal of betafite showing defined octahedral faces (triangular) and developed dodecahedral ones. Very interesting for its crystallography and species. An oldie, classic and representative for the species.
Although the term betafite was discredited in 2010, many of us still are using this term to define this mineral when we see it. Our specimen is an uranium, calcium, titanium and niobium/tantalum oxide with radioactive activity. Currently the betafite is included as a variety within the pyrochlore supergroup. As a note, the rich uranium term has been only found in the Moon (oxyuranobetafite).

Size: 4.8 x 4.4 x 4.1 cm.

Presents radioactive activity.

Elongated cubic fluorite crystal of very good size, with tile growths on the faces. Between translucent to transparent and with a very uniform violet color. It is complete on both sides and is placed on a small matrix with quartz.
