Shattuckite after Barite - Shangulowe Mine, Kambove, Haut-Katanga, Democratic Republic of Congo

An unusual and highly attractive shattuckite specimen from the famous Shangulowe Mine in the Democratic Republic of the Congo. Rather than occurring simply as massive material, the shattuckite has replaced earlier-formed barite while preserving its distinctive bladed crystal habit, creating an excellent example of mineral replacement.
The specimen is richly covered with vibrant blue shattuckite, with intricate bladed and radiating structures visible across the matrix. The combination of intense colour, unusual pseudomorphic form and substantial size makes this a particularly interesting example from a world-class copper-mineral locality.
The specimen is believed to have been collected prior to 1959, according to an earlier label that accompanies it. Ex Brenton Mah Collection and ex Robert Verdoot Collection. From the Shangulowe Mine, Kambove, Haut-Katanga, Democratic Republic of the Congo.
