Summary edit

Description
English: Boleite, Cumengite, Pseudoboleite
Locality: Amelia Mine, Santa Rosalía (El Boleo), Boleo District, Municipio de Mulegé, Baja California Sur, Mexico (Locality at mindat.org)
Size: thumbnail, 0.8 x 0.8 x 0.7 cm
Cumengeite and Pseudoboleite on Boleite
This is an exemplary example of the epitaxial, or oriented serial growth, of these rare species one upon the other, with sharp form and good color as well. The Cumengeite is the sharp, pyramidal-like outgrowth popping out of one face of the central cube. All of the steppes upon the original simple cube of Boleite are in fact the related species Pseudoboleite. Thick Pseudoboleite epitaxially overgrew the Boleite cube, showing quite clearly even to the naked eye. Interestingly (and I never realized this until now), only boleite is a silver species - the other two have no silver content. The crystals of all 3 species from this, the type locality, remain the best known by an order of magnitude, still today 100 and more years later. ex. Dick Jones collection (TYPE LOCALITY)
