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...
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.
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.

After a trip to Morocco in 2013, we analyzed few samples of a mineral similar to mimetite species. Results indicated that it was phosphohedyphane. From the same mine we have obtained some specimens of the zone in which came out in 2013 original ones, but now they showed marked differences. After a careful analysis, results indicate that these were also phosphohedyphane, but with a different shape but similar to the pyromorphite appearance. They are covering cavities of the limonite matrix, small hexagonal crystals slightly barrel-shaped, with green to a yellowish tones. Accompanied by brilliant quartz and vanadinite, some rich in arsenic. It seems that they form part of a pyromorphite-phosphohedyphane series. Analysis results will be delivered to the buyer.

These curious specimens from Taouz mine were collected in February 2013. These cavities are covered by hexagonal prismatic crystals of greenish to yellow color, opaque to translucent, forming nice aggregates. Interestingly, some of the cavities are coated by brilliant small quartz crystals, giving an excellent contrast to the specimen. Iniatilly, these crystals were identified as pyromorphite, but after new SEM-EDS analysis, we can confirm that these crystals contain calcium, with chlorine, phosphorus and lead.

This is the first citation of this species in Taouz.
These globular vanadinite aggregates, formed by hexagonal crystals, were collected Taouz mine few days before our visit. These groups, which are sometimes partially covered by calcite, are very brilliant, translucent and they are disposed on the matrix covered by lenticular goethite. A new Taouz curiosity.
A very nice huge size goethite specimen showing stalactitic-habit, well developed, with aesthetic botryoidal forms. Exterior color is olive green, with very curious terminations, very thin. We can observe that these growths are formed by several goethite crystals in radial disposition. A high quality specimen for this Moroccan mine.
A very nice specimen of goethite showing stalactitic-habit with botryoidal forms. Exterior color is olive green, with very curious terminations. In the base we can observe that these growths are formed by several goethite crystals in radial disposition. A quality specimen for this Moroccan mine.
This specimen was collected a few days before our visit to the mine. A group of vanadinite crystals with a hexagonal shape and forming nice globular aggregates. The color is orange to reddish, with good transparency and disposed on vugs in the compact limonite matrix, covered by small goethite lenticular crystals. A not very common specimen from this classic mine.
