Clusters to 1mm of lustrous green Cuprian Austinite. The Scott Williams label that came with this piece says it is from Serpieri Mine, Laurion, however Austinite is not listed as occuring at Serpieri on Mindat and the Cuprian Austinite from the Hilarion Mine is very similar to this piece. There is also some uncertainty as to whether this is Austinite or Adamite, and at this scale they are difficult to distinguish.
