This specimen is not only aesthetic, it also incorporates the best assemblage of species for a Mapimi wulfenite. A rich, gossany, limonite matrix gives way to a superb, botryoidal, translucent, green mimetite crust upon which are perched isolated crystals of lustrous and translucent, pseudocubic, butterscotch-colored wulfenite to .9 cm in length. The presence of a fine quality mimetite on the limonite is not common, and this piece really is rich in it.
