A novelty at the 2020 Munich Virtual show. Matrix group of Ullmannite crystals of cubic habit, with well defined faces and edges, of considerably large size for the species and with small interstitial coatings of nickel salts. As is inevitable with this type of crystals included in the interior of a Calcite matrix, it has been partially acid-etched. The specimen, which comes from a new Moroccan locality for which at the moment we only know the region, has been analyzed. Souss-Massa Region, Morocco. Found in: 2020. Reference: EA6AM1
