A striking and well-balanced specimen featuring lustrous bournonite crystals intergrown with vibrant, brassy chalcopyrite on a bed of clear to milky quartz. The bournonite displays excellent metallic luster with characteristic cogwheel formations, while the fresh chalcopyrite crystals add vivid contrast and sparkle.
This piece originates from Peru, a classic locality for sulfide combinations, and comes from the historic mineral collection of Richard Valentine Cain (London, UK) — acquired on the UK mineral and fossil market post-1970. Accompanied by both an original Gregory, Bottley & Lloyd label and a historic hand-typed collection index card, adding desirable provenance and collector appeal.
A fine example of Peruvian bournonite for both advanced collectors and those seeking classic, old-label sulfide material.
