Spring update

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.

Bright glassy clear crystals of light pink-violet Calcite perched on a contrasting amethyst matrix. Classic material from Guanajuato, this is quite eyecatching.
