Vivianite is a hydrated iron phosphate mineral with the formula Fe₃(PO₄)₂·8H₂O. Fresh material can be very pale, while oxidation is associated with the blue, blue-green and greenish-blue colours collectors often recognise. It crystallises in the monoclinic system and can form flattened or bladed crystals.
