Pyrargyrite (Ruby Silver crystals) (Ref: AX-29-047)

Super lustrous, metallic crystals of Pyrargyrite in a cluster with no matrix. Many of the larger crystals are distinctly twinned. These look silvery-black without very strong lighting but a few edges show the bright red flash and glint of the "ruby" color. The crystals are opaque for the most part but a few edges show some translucence. A mid 1980 vintage Silver secondary specie from the famed and prolific San Juan de Reyes Mine (Guanajuato, Mexico). A hefty thumbnail in good condition, there is some roughness and the backside is the point of removal but this is still in better shape than usual for this delicate mineral. The Ruby Silvers of Mexico are now considered classics and are quite different than the old European specimens. Choice.
