A large cabinet sized sample of bournonite from of of the less prolific Bolivian mines, as far as specimens as concerned. The deposit was discovered in 1833, and was finally abandoned in 1990.
This piece is composed almost entirely of sulfide material, and hosts numerous blocky bournonite crystals, displaying the classic cogwheel form. Most of the Bolivian bournonites offered for sale these days are from the Machacamarca Mine.
