RM3455   Djurleite-Chalcocite

The first specimens were found in the mines of Aït-Ahmane between 2014 and 2015. The best ones reached the market around 2017. They are twinned crystals of remarkable perfection for the species, formed by intergrowths of djurleite and chalcocite. No better specimens have been found in the area and probably worldwide.
Although some relatively recent analytical results (see mindat) indicated that they were crystals of djurleite only, others indicated that they were mixtures of both species. Realistically, djurleite and chalcocite often appear together in the same crystal, and one can even transform into the other depending on the physical-chemical conditions present. For this reason I have preferred to preserve the name of both species. Interesting article: Pósfai-Buseck Amer. Min. 1994.

Size: 7.5 x 6.2 x 3.5 cm.
Main crystal: 13 mm.

RM3452   Blue wulfenite

A very faceted tabular crystal of wulfenite. It stands out for its deep blue colour, which is unusual for this species. It belongs from the Bou Skour mine, where crystals of this type have been obtained, but they are usually very small, around a millimetre. This one measures 8 mm...

RM3239   Goethite and quartz

This specimen is totally different from those that we usually see in the market of this Moroccan locality. The matrix is a group of quartz crystals, with a soft amethyst tone, and partially covered with chalcedony, in tiny, shiny crystals. On this matrix there is a large group of goethite crystals, lanceolate, dark brown in color and also covered with chalcedony. But millimeter quartz crystals stand out above them, most of them doubly terminated. I had never seen specimens that looked like this. Very interesting.

Size: 9.6 x 6.5 x 4 cm.
