Cornetite


Cornetite is a hydrous copper phophate. Cesáro (1910) originally noted the mineral at L'Étoile du Congo. However the species remained unnamed until Buttgenbach (1916) named the mineral after Jules Cornet (1865-1929). A later study by Berry (1950) further describes the history of its discovery.

This specimen consists of a slate matrix covered one side with drusy blue cornetite. This locality is distinct from the type locality, and less often seen in collections. This is very rich for species, as cornetite does not typically completely cover a surface of matrix. A dealer label from Gilbert Gauthier (1924–2006) accompanies the specimen.
