Description
Here we have a bright, well-formed metallic grey tabular crystal of Bournonite, measuring to 4mm, perfectly perched in a Quartz druse specimen, from the Vojtěch Mine of Březové Hory ( Birkenberg in German ) at Příbram mining district . The pristine Bournonite has superb metallic sheen, is rich of faces and has woderful striation as well. Old-time and very rare material, meanwhile exceedingly hard to come by. Comes with TWO fine old labels.
