A beautiful much sought after blue colour specimen of Willemite, greatly enhanced by the formation on Cerussite crystals from the mineral mecca of the Tsumeb Mine, Namibia. The specimen of Willemite we have to offer displays excellent single cauliflower form groups measuring to 0.8cm diameter, with a crystalline surface to them. Willemite also forms a lovely botryoidal covering to the reverse of the specimen, on a reticulated habit of glassy Cerussite. A fine translucent pastel blue colour is seen to the Willemite set pleasingly on the colourless to smoky Cerussite crystals.
