In this specimen we have a very curious combination of erythrite forms. On the one hand, globular aggregates of this arsenate formed by needle like crystals with a velvet luster and a pale pink color. On the other hand, groups of lanceolated crystals with defined faces and edges, good transparence and deep purple color. All of them are disposed on a matrix with sharp cube octahedron skutterudite crystals. A fine specimen for this Moroccan locality.
