Malachite replacement after well-formed bladed monoclinic Azurite crystals is the classic pseudomorph one thinks of when Tsumeb mine is mentioned. This superb miniature specimen is dominated by a quite large (4.6 cm in length) and quite chunky terminated monoclinic pseudomorph accompanied alongside by at least 15 smaller but equally well-formed pseudomorphs. All of these pseudomorphs show total replacement by Malachite and are sat upon a pale pink-cream carbonate (Dolomite or Calcite) matrix. A partial coating of murky-green Duftite microcrystals can be seen on the matrix, both on the front and back. This association of Malachite pseudomorphs after Azurite with Duftite is unique to Tsumeb. Ex Martin Kershaw Collection.
