RM2269   Wulfenite with barite

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.

RM2145   Vanadinite on goethite
More photos

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...

RM2058   Hematite

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.

RM2057   Hematite

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.

RM1979   Vanadinite with Baryte
More photos

Floater specimen. Excelent group of vanadinite crystals showing a defined hexagonal shape, with very well defined faces and edges, intense red color. Good brilliance and some transparence, with internal reflections between red and orange. Crystals size is remarkable. A piece with two faces. One of them, crystals are disposed in an isolated way on a barite lenticular rosette crystals. In the other, they are forming rich crystalline groups. The presence of this baryte matrix is highly appreciated by collectors and gives to the specimen a special aesthetics.

RM1789   Malachite with limonite
More photos

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.

RM1771   Vanadinite
More photos

Excellent specimen of vanadinite formed by several medium-sized crystals, on which groups of larger crystals have been grown. They show the shapes of the hexagonal prism, with slightly striated faces, and with smooth pinacoidal faces. The brilliance and color are more than exceptional. It presents a very intense garnet red color in the central areas of the prism and a redder tone in the pinacoids. Under the incident light it is spectacular. This specimen comes from the ACF shaft, in Mibladen, and was mined on February 6, 2018 and we were very lucky to be there. Pieces with this crystal size and quality are very unusual...
