An incredibly rich and, and equally important, PRETTY, Tsumcorite specimen with real display quality! Tsumcorite is one of the signature mineral rarities for which the Tsumeb Mine is renowned and is also the Type Locality. Tsumcorite is a lead, zinc, iron arsenate and is named after the Tsumeb (Tsum) Corporation (Cor) Mine. Orange-brown radial clusters of Tsumcorite up to 6 mm richly and aesthetically cover much of the matrix and are complemented by a multitude of tiny Quartz crystals. Also, many of the spheres have additional clusters of Tsumcorite growing on them, which I have not seen before in such quality. Quartz is uncommon at Tsumeb. Specimens of this caliber are EXTREMELY rare and this is a major piece for any Tsumeb collection, rare or common.
