6 smooth and well-formed cumengeite points, some with naturally truncated ends, others pointed, developed in epitaxy on the faces of a boleite crystal, the whole forming a set, considered large for the species, that is quite symmetrical with a beautiful deep blue color. This sample has been collected in the 1920s by the director of the Boléo mine, Albert Bellanger.
