A fine bubbly display of botryoidal Willemite from the Tsumeb Mine, Namibia. Translucent pastel blue to slightly tinted green Willemite has a sparkling surface. A partial formation of colourless to white crystals of Dolomite has developed in areas on the Willemite. The Willemite has to a large extent over grown a previous deposition of green Duftite on and in a reddish Dolomite matrix.
