A SUPERB, two-sided willemite specimen from the famous and now-closed Tsumeb Mine. Powder-blue Tsumeb willemite is RARE, but this beautiful piece has vuggy matrix on both sides lined with lustrous, powder-blue willemite botryoids! A dusting of malachite really adds pizzazz on one side. There is even an 8 mm, lustrous, yellow mimetite hidden in the willemite botryoids! EXCELLENT material from the Rob Smith Collection, a noted Tsumeb collector.
