A EXCELLENT and AESTHETIC, OLD-TIME Tsumeb specimen of lustrous, caramel-colored wulfenites attractively set on contrasting quartz needle-covered matrix and FURTHER enhanced by the blue-green copper sulfate oxidation minerals devilline and serpierite. ALL of the major wulfenites are PRISTINE and the large complex crystal is 1.4 cm. The old, 1970s or early 1980s, dealer label misidentifies devilline and serpierite as rosasite.
