Rare Cumengeite specimen just released for sale by a Mexican miner. Cumengeite is a rare halide that grows on the faces of Boleite cubes. On this specimen, there are pointed crystals of Cumengeite on 5 of Boleite cube faces and a flat Cumengeite or psuedoboleite on the remaing cube face. Although not a perfect star, these are hard to come by.
