Cool Boleite Avant Garde Gemstones




Boleite was first found out in Boleo, Mexico in 1891, in a very area with the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its 1st discovery.

The initial specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the very same area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
