Polybasite w/ Quartz (excellent - classic locale)

Item Description

An exceptional polybasite from the famous Rayas Mine or from ANY of the well-known silver mines at historic Guanajuato. Polybasites with this outstanding sharpness and aesthetics are VERY RARE from here. The pseudo-hexagonal twilling has textbook tablet form on BOTH sides. The lustrous metallic plates are beautifully accented with small quartz crystal on one side. "World-class specimens of polybasite are among the glories of Guanajuato" (Guanajuato article in the Mineralogical Record Mexico-VII Special Issue, September-October, 2016). The bit of noted bruising on the top line certainly has minimal impact to the overall top quality of this superb miniature. Valued at $2500 and competitive quality
