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.

Size: 6 x 5 x 3.2 cm.
Main crystal: 12 mm.

These specimens are formed by numerous prismatic crystals of orthoclase, 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.

Main crystal: 5 mm.

Fan-shaped aggregates of epidote crystals with an intense green color and luster. They are accompanied by hyaline quartz crystals and fine olive green actinolite needles. A different specimen from this classic Moroccan locality.

Size: 8,6 x 6,5 x 5,2 cm.
Main crystal: 2 cm.

A really interesting good size and gemmy fluorapatite crystal. We can observe perfectly the combination of the first and second order prisms; very sharp terminal faces, with first order hexagonal dipyramid. A specimen to enjoy crystallography and aesthetics.
Crystal shows excellent brilliance, transparence and a vivid yellow color with green tones. The specimen is from a Moroccan classic mine located in the Imilchil mountains area.

Size: 2.6 x 1.3 x 1.2 cm.
Found in ca. 2012.

Classic locality

Very aesthetic and good sized specimen of hollandite, with stalactitic botryoidal structures, velvety and intense almost black gray. A quality piece from this classic Moroccan mine.

Curious specimens of vanadinite showing yellow, slightly orange, hexagonal prismatic crystals, on which a thin layer of goethite has been deposited. At the same time, on this layer another generation of vanadinite and calcium-rich pyromorphite (phosphohedyphane), such as the attached analyzes show, we will send to the buyer. They are disposed on a matrix of goethite. Very interesting and different specimen from this classic Moroccan mine. Take a look to the SEM image of second generation crystals with an unusually rich facet...

Analyzed specimen with report

Brilliant botryoidal hematite specimen. In the back side we observe very esthetic concentric growths of different colours, fibrous, of hematite. These pieces have been cleaned in origin with sand which eliminates the surface oxide layer to let us see these spherical forms of good size. Very curious Moroccan novelty.

Good botryoidal specimen of hematite. In the back side we observe very esthetic growths of different tones, fibrous, of hematite. These pieces are usually cleaned at the origin with sand, but in this case and because of the luster, we do not believe that it was. Very curious Moroccan novelty.

Excellent stalactitic coronadite specimen, analyzed by SEM-EDS, with rounded shapes, intense gray almost black. Good size. From this classic locality for Moroccan mineralogy. With yellowish goethite matrix. You can find more information about this species and locality in the Rosell Minerals blog.

Size: 10.8 x 6 x 3.5 cm.

This specimen shows an arborescent growth with deformed crystalline forms and other idiomorphic in some areas of the specimen, with well defined faces and edges. With good color and brightness which is not very frequent. With small quartz crystals.

Aesthetic aggregate of very sharp tabular marcasite crystals, brilliant, with very well defined faces and edges. A couple of breaks that are not easy visible, but complete in my opinion. On quartz matrix.

Size: 8.2 x 6.2 x 3.8 cm.
Main crystal: 17 x 10 mm.

Very rich group of pseudorhombohedral and interpenetrated crystals of malachite, very sharp. It would seem to be primary but in my opinion it is a total pseudomorphic substitution after azurite crystals. The brightness is good, intense green color, forming aesthetic aggregates. They are disposed into cavities of the goethite matrix (limonite) with quartz. Excellent specimens rarely seen in collections.

Size: 5.5 x 3.5 x 3.0 cm.
Main crystal: 8 x 6 mm.

Aesthetic group of elongated, fan-shaped and very well defined prismatic crystals of malachite, it would seem to be primary but in my opinion it is a total pseudomorphic substitution after azurite crystals. Accompanied by a azurite brilliant crystal. The brightness is excellent, intense green color, forming divergent aggregates. They are disposed filling cavities of the goethite matrix (limonite). Excellent specimens rarely seen in collections.
