Dark green crystals of Kolwezite and/or Malachite that has pseudomorphed after Barite (?) on Cobaltian Calcite. The pseudomorphs form a cluster about 4cm wide in a vug. The Cobaltian Calcite is brown with an later generation of vivid pink. Kolwezite is a Copper Cobalt Carbonate Hydroxide and this is the type locality for the species. private_notes
