An excellent specimen of Wulfenite from the Tsumeb mine, Namibia. Lustrous caramel coloured crystals of Wulfenite measuring to 1.7cm on edge mostly stand upright on the specimen. The crystals of Wulfenite show well developed striated bevel edges and large flat faces. A later deposition of prismatic crystal clusters of lemon yellow Mimetite are grown on and amongst the Wulfenite. The matrix is a mixed colourless to white Quartz with black to red brown Goethite.
