Capgaronnite (•) is a mineral that forms small tufted aggregates or isolated crystals with a maximum width of 0.02mm and a maximum length of 0.1mm. This mineral is related to perroudite in chemical composition and crystal structure. Capgaronnite is associated with secondary minerals of Cu like olivenite, cyanotrichite, and tennantite.
