Duftite is a lead copper arsenate mineral that typically forms as radiating, prismatic to tabular crystals in oxidized zones of arsenic-bearing hydrothermal veins. It commonly presents a yellow to brownish hue and can show a vitreous to resinous luster, sometimes occurring as aggregates or crusts on matrix. Crystals are often small, but well-formed specimens from certain localities can be striking, reflecting the mineral’s earthy color and glassy facets.

About Duftite
Notable specimens come from regions with rich oxidized ore deposits, including Namibia, the United States, and Mexico, where Duftite forms alongside other arsenates and carbonates in manganese- and lead-rich environments. Collectors prize Duftite for its clean, translucent color, variable habits, and the way it records the geochemical history of its host rocks. While not among the largest or most dramatic minerals, Duftite offers pocket-sized elegance and interesting associations with supporting minerals in classic arsenate suites.
