Polybasite on Acanthite
Guanajuato, Municipio de Guanajuato
Guanajuato, Mexico
3.2 x 2.4 x 1.7 CM (thumbnail)
price: $3200


A killer specimen with exceptional form, the main crystal being textbook perfect, sharp and perfectly defined. Formerly in the collections of Carl Acosta and Brett Keller, this is just barely within the size limit to be classified a thumbnail. The Acanthite matrix is the "melted" look type and is a fine contrast to the large Polybasite. Displays well from either side, what we consider to be the front or best view has a nice metallic patina. Most of the Polybasite we have seen from Guanajuato is more crude or has overgrowths of Pyrite, this is just a superb example of the specie and extraordinary for the locality.
