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.
Found in ±2002.

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.
Found in ±2008.

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.

In this specimen we can observe some groups of tabular wulfenite crystals of intense, very intense orange color, showing defined faces and parallel growth. If anything distinguishes these wulfenite crystals is its vivid color. The brilliance is excellent and in thin areas show transparence. Some of the dominant crystals are disposed very aerial and accompanied by groups of barite crystals. If you observe closely the specimen under the microscope you will see numerous perfect tabular crystals of wulfenite. Very aesthetic specimen.

Size: 7,5 x 5,7 x 4,0 cm.
Main crystal: 1.7 cm.

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.

Size: 10 x 6 x 5.5 cm.

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...

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.
