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 add to the quality and lively brilliance of their iridescence in metallic, blue, ocher, and reddish tones, with greyish metallic reflections predominating.
