Acanthite and Polybasite on Quartz
San Juan de Rayas Mine, Municipio de Guanajuato
5.7 x 4.4 x 2.3 CM (cabinet)
A melted look sculpture of Acanthite crystals on Quartz also holds a few small Polybasite crystals in sharp hexagons. Choice older piece from the San Juan de Reyas mine in Guanajuato. In excellent condition as seen and with a nice dark metallic patina. Under 20 X magnification I can see glints of blood red color that indicates at least a tiny bit of Ruby Silver (Pyrargryite) is also present but very small.
