A group of five bournonite crystals, all showing to some extent the 'cogwheel' crystals structure common for the species. Other sulfide and/or sulfosalt species such as stannite may also be present. None of the specimens are perfect, but this lot provides a good representation for the species and locality. Collected in 2013.
