Description
The Viboras mine at Machacamarca in Bolivia is particularly famous for its Bournonite. This fine miniature features a single Bournonite crystal, 1.7 cm long by 1 cm thick, sat in the centre of a Quartz matrix encrusted all round with micro-crystals of Quartz. There is also a rich coverage of sooty black micro-tetrahedral Freibergite crystals with tiny Pyrite crystals sparsely scattered all over. The Bournonite crystal forms an excellent cogwheel habit of steel-grey with a bright metallic lustre.
Known provenanceKnowing where your specimen comes from and who owned it adds to its story and value. Good provenance helps prove it's authentic and preserves important details about its discovery.
