This superbly crystallized thumbnail phosphate specimen from Jocão Pegmatite in Minas Gerais, Brazil from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021) was labelled as Reddingite, but published data suggests that all Reddingites from Jocão Pegmatite are the new species Correianevesite: an iron manganese phosphate hydrate. This thumbnail is an aggregate of well-formed glassy equant Correianevesite crystals, the largest crystal reaching 5 mm across. The crystals cover all sides of this small specimen, with no obvious point of attachment to matrix. Individually, the crystals are lovely wedge-shaped flattened octahedra, and display a fine resinous lustre. A superb example of this new species.
