Aggregate, on matrix, of very well defined and bright Covellite microcrystals. They have an intense metallic blue iridescence. The sample is from a find in 1996. Subsequent finds have been sporadic, practically non-existent, either in that zone or the rest of the mine, which currently is now completely inactive.Corta Atalaya, Pisos 14-16, Minas de ...

Black crystal of Gratonite dimension crystal mm. 1,2 photo Germano Fretti collection Luigi Chiappino
