Comment: An old-time, very showy Tsumeb specimen of blue-green rosasite richly covering one side of a very 3-dimensional matrix of sparkly dolomite, which is probably zinc rich. Rosasite of this quality and combination is RARELY available from Tsumeb. The contrast is striking. Ex Rob Smith Collection, a noted Tsumeb specialist.
Minerals: Dolomite (CaMg(CO3)2) Rosasite ((Cu,Zn)2(CO3)(OH)2)
