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.

RM1771   Vanadinite
Pb₅(VO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

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...

RM1665   Nepheline and schorlomite

A vug that is lined with sharp, hexagonal, grayish-white nepheline crystals, accompanied by lustrous, black crystals of schorlomite as dodecahedral crystals. Schorlomite is a rare garnet group member and much of the material labeled "schorlomite" is, strictly speaking, titanian andradite. Excellent, highly representative combination material of the species. Not very often one can see well formed nepheline crystals of this species, especially crystals this size. Very aesthetic specimen from Jebel Bou-Agrao.

RM1220   Twinned cerusite with barite and galena
Pb(CO3)
  -  5. Carbonides and nitrates

In this huge size specimen we observe groups of tabular lenticular aggregates of barite with a delicate reddish tones, along with gray galena that has been almost completely substituted and covered by nice cerussite crystals. Taking a look under the microscope, cerussite shows long striated prisms terminated by pyramidal faces. Also note several cyclic star twins, well defined and spectacular. Different specimens from Mibladen.

The large mine of Les O is mined under the town of Mibladen. It has been worked during generations of miners in search of specimens, usually galena cerussite, barite and some wulfenite. Few weeks before my visit in February 2013 were found some mineralized veins and vugs with the specimens we offer. When those cavities were formed they had been filled by cube octahedral crystals of galena and barite. Due to the hydrothermal fluids galena was partially or totally corroded to favor the formation of cerussite.
