Tiny but super-rare, this cumengeite crystal perches on a throne of brecca, or broken-up rock and mineral naturally cemented together. Cumengeite is closely related to boleite, which forms cubes of a similar blue hue and is found in lead and copper deposits. This cumengeite measures just a centimeter across and comes from Mexico.
