Although not the Type Locality, and no longer the world's largest crystals, there is something enduring about the 'cogwheel' twinned Bournonite crystals that were found at Herodsfoot mine in Cornwall during the 1860s. So cherished and collectible, cabinet-sized specimens fetch significant sums and are out of reach of most collectors. This is where this miniature Herodsfoot Bournonite comes in. Admittedly small, and with some age-related bruising of the Bournonite crystals, it actually presents the classic all-round qualities of this most important of finds extremely well, with a clear, well-formed gun-metal grey 'cogwheel' running upright across the middle. Not only this, but this and the other crystals show the distinctive one-sided overgrowth of stumpy Quartz crystals down one edge of the blades of Bournonite. Finally, the matrix contains fudge-coloured Siderite. A true Cornish classic that exudes charm. Ex Cedric Rogers Collection and ex Glyn Cunnick Collection.
