Vauxite is a hydrated iron aluminum phosphate mineral. It forms as a soft, earthy to micro-crystalline mass, often displaying a green to yellowish color and a dull to submetallic luster. The mineral commonly occurs in phosphate-rich deposits and is frequently found in association with other secondary phosphates, reflecting its formation under relatively low-temperature, near-surface conditions. Notable specimens have been reported from Bolivia and the United States, where secondary mineralization in oxidized phosphate zones provides the solitary pockets that preserve delicate, often botryoidal or tabular aggregates. Its fragile, layered to plate-like habit makes high-quality pieces especially prized by collectors who seek unusual phosphates with a history of occurrence in classic localities.
