Arsendescloizite
2 in the gallery
Arsendescloizite is a lead zinc arsenate mineral that forms in short, tabular or prismatic habits with a metallic to submetallic lustre. Crystals are typically brown to olive in color, sometimes with greenish or yellowish tints, and they may occur in association with secondary ore minerals in oxidized zones. The mineral commonly appears as compact aggregates or single crystals that display a characteristic reflective sheen when cut or polished.

About Arsendescloizite
Notable specimens have been reported from Mexico and Namibia, where oxidized zones of zinc-bearing lead ores provide the hydrothermal environments needed for its formation. Collectors prize well-formed crystals with clean terminations and strong luster, as well as matrix pieces showing contrasting minerals that enhance its aesthetic appeal. Its rarity and distinctive arsenate chemistry add to its interest for cabinet display and mineral study. While not among the most abundant species, arsendescloizite remains a sought-after piece for its combination of color, crystal form, and locality associations.
