Description

A nice old timer - and a rare one too: specimen with silky aggregates of malachite together with deep blue azurite on whiteish baryte crystals. Comes with old label, dating the specimen to 1848 or earlier. For help in deciphering the locality written on the label my thanks go to P. Haas (cheers!).
