Here we have a wonderful and also interesting combination piece from well known Tsumeb Mine of Namibia. In this specific case we see numerous, sharp and tabular, slightly intergrown Wulfenite crystals richly perched on sculptural, Mottramite-covered matrix. The Mottramite has light-green to olive green colour and features a glistening surface. The Wulfenites are sharp, but beveled edges, highly lustrous and lucent to transparent. Highly interesting combo from the Peter Döring collection.
