Bolivia is famous for rare minerals and unusual assemblages. Here is one! These specimnens are all excellent specimens of native bismuth cleavages. Interestingly there are crystals of joseite embedded into the bismuth, often beside quartz crystals or in cleavage planes. THe joseite has been analysed by both x-ray and EDS analytical techniques and confirmed to be joseite. Some are absolutely excellent specimens of joseite. All are excellent native bismuth specimens!
