Description

A fine sample from this latest discovery from this famous old silver and cobalt mine. It worked intermittently during the 18th century. It was restarted in 1832, but had to close again in 1837. So really a great German classic in fine quality! The highly lustrous crystals are translucent, their color is bright yellow, some crystals show this typical but amazing blue phantom. No significant damages to report, backside was on the  rock.
