Chysocolla and malachite
description: LOCALITY: Star of Congo Mine, near Lubumbashi (formerly Elizabethville), Katanga Province, Democratic Republic of the Congo  2 7/8" across This specimen consist of botryoidal, aqua-blue chrysocolla with botryoidal, chatoyent malachite on matrix. Star of Congo Mine was a major producer of mineral specimens prior to around 2001.  This piece was bought during a visit to the Congo in late 2009. Although chrysocolla from this mine is not uncommon, this one is particularly esthetic.     Photo by Matthew Webb of Melbourne, Victoria, Australia
