Manganite is a manganese oxide with hydroxide, forming as isometric to monoclinic crystals in layered, platy aggregates. Its color ranges from deep olive green to black, and it often displays a metallic to earthy luster on exposed faces. Specimens typically form in oxidized zones of manganese-rich deposits, assembling as lath-like or tabular crystals that can be highly lustrous under good crystallization.

Notable localities include historic manganese deposits in Germany and world-class find sites in South Africa, the United States, Mexico, and Canada. Collectors prize well-formed, sharp crystals with rich color and clean faces, as well as specimens showing dramatic fan-like groups or distinctive rosettes. Manganite’s relative rarity and striking habit make it a sought-after material for display as individual crystals or cabinet-sized clusters, often pairing well with other manganese minerals for contrast. Its attractive morphology and bold coloration help it stand out in a collection focused on oxide minerals with strong optical character.
