Jouravskite is a very rare hydrated sulfate found at only three localities worldwide. Two are in the Kalahari Manganese Field. A "board" of massive manganite is strikingly covered on both sides with a vivid, lemon-yellow crust of fibrous jouravskite. Very highly representative and very rich for the rare species and from the N'Chwaning II Mine. The lemon-yellow color is much more vivid in person.
