NC9AM1: Compared to other Goethites in southern Spain, those from the La Lapilla mine stand out for their delicate lattice growths and very fine arched structures, sometimes almost filamentous, which adds to the quality of their soft iridescence, with pastel blue, ocher, and reddish, although greyish metallic reflections predominate.
