Kolwezite is a copper cobalt carbonate hydroxide mineral. It forms as small to medium-sized, typically botryoidal to tabular crystals and crusts, often displaying a green to bottle-green coloration with a vitreous to resinous luster. It is associated with hydrothermal, secondary oxide, and carbonate-rich environments, where copper and cobalt can co-precipitate under oxidizing conditions.

About Kolwezite
Notable specimens have come from the Democratic Republic of the Congo, where secondary sulfide and oxide zones can produce concentrated pockets of kolwezite in oxidized copper-cobalt deposits. Collectors value it for its distinctive pale to deep green tones and its relatively rare occurrence, which makes high-quality matrix specimens sought after by mineral enthusiasts. When clean and well-formed, kolwezite crystals and aggregates can display pleasing transparency and interesting crystal habits that photograph well under reflected light.
