Crystal specimen -Pigeon blue -Chalcedon with Siderite xx
Dove blue CHALCEDON . The Celts and Romans already extracted the coveted Noric iron ore from this mining area over 2000 years ago.
Top specimen with clustered chalcedony xx on SIDERITE xx. Only few collectors own such a specimen. The Hüttenberg mining industry has been closed down for 40 years and therefore there will never be any new steps from here.
