Vivianite is a hydrated iron phosphate mineral that commonly forms as columnar, tabular, or fibrous crystals. Its color ranges from colorless to blue-green or blue under reflected light, often darkening with dehydration and exposing a pale blue to emerald tint in polished surfaces. The mineral typically occurs in secondary phosphate deposits associated with iron-rich shales, and can exhibit a glassy to silky lustre with a vitreous sheen.

Notable specimens have been reported from Bolivia, the USA, Ukraine, Brazil, and Germany, where it occurs in phosphate-rich pockets within sedimentary rock or near ore dumps. In some locales, vivianite forms as vibrant blue crystals in siderite- or pyrite-bearing hosts, sometimes coloring surrounding minerals and soils due to oxidation. Collectors prize well-formed crystals that display clear zoning, crisp terminations, and deep blue hues, as well as crystals that retain hydration for vivid coloration.
