A richly adorned crystal specimen of Bournonite with Chalcopyrite on Siderite from the Georg Mine, Willroth, Germay. Crystals of Bournonite measuring to 0.9cm are abundantly intergrown over most of the display face of the specimen, with a sharply developed wedge-like habit. Iridescent metallic reddish crystals of Chalcopyrite are dotted over the Bournonite crystals. A light biscuit coloured crystal druse of Siderite is the host for the Bournonite, on a dense matrix of Siderite with veinlets of Chalcopyrite. A brilliant specimen from the mine.
