Rare Cumengite specimen just released for sale by a Mexican miner. Cumengite is a rare halide that grows on the faces of Boleite cubes. There are pointed crystals of Cumengite on all 6 of the Boleite cube faces, 5 of which are perfect, one with a micro ding. Rare to find complete 'stars' or 'jumping jacks' of Cumengite.
