6 in the gallery
Minium is a lead oxide mineral with the formula Pb3O4. It typically forms as deep crimson to brownish-red tabular crystals and can occur in crusts or aggregates with a submetallic to dull onyx luster. Specimens are often associated with oxide-rich hydrothermal environments and high-lead environments, presenting a striking color that stands out in mineral collections. Notable localities include occurrences in the United States and Iran, with additional finds in Australia and Namibia contributing to its worldwide array of classic samples.

About Minium
Collectors prize minium for its vivid coloration, crystallographic habit, and its role in historical lead ore oxidation zones. It often appears alongside other lead oxides and sulfides in oxidized zones of ore deposits, providing appealing contrasts in display assortments. While it can be less common than some oxides, well-formed crystals and botryoidal masses from premier mines offer attractive, collectible pieces that highlight the mineral’s characteristic hue and metallic sheen.
