Vivianite is a hydrated iron phosphate mineral with the formula Fe₃(PO₄)₂·8H₂O. It forms colorless crystals that darken to deep blue or green upon light exposure due to oxidation. Vivianite occurs in sedimentary environments, peat bogs, and as a secondary mineral in ore deposits. Crystals are usually prismatic and can reach impressive sizes. Major sources include Bolivia, Germany, Ukraine, and the USA. This page explores vivianite’s properties, structure, and significance in mineral collections.
