Djurleite-Chalcocite intergrowth.
TB37AG6: Djurleite-Chalcocite intergrowth
There are few good Djurleites left from the ones recovered at the Aït Ahmane Mine between 2014 and 2015. We were lucky to be able to gain access to the finest pieces during Tucson 2017 and we still have some of great quality. This one in particular is the best we have left. These large crystals with good definition, both on the front and on the back, and with some minor matrix makes an excellent specimen.

JFD69AO0: Dolomite
Due to their transparency, these dolomites are considered, together with those from Brumado, Brazil, the best in the world. In some cases, this transparency can be overwhelming, as can be seen in this very well-formed specimen which, curiously, is not from the golden age of the Asturreta Quarry, when engineer Córdoba was extracting wonders from the El Pozo area, but rather later, from the upper levels of the Azcárate Quarry.

The Daunis collection is a faithful mirror of the minerals that were found in Spain in the 60’s and 70’s.

This piece is a good example.
