Shangulowe Mine, Kambove District, Katanga, Democratic Republic of Congo

Individual, prismatic crystals of barite, to 1.1 cm in length, on matrix, have been pseudomorphed (replaced) by grass green malachite. Another fine, rare specimen from this find of the late 1990s. I have not seen this quality since, and they seem fairly unique for overall quality and sharpness.
