Silver, Calcite – Batopilas (MEX)

This thumbnail specimen is an outstanding example of this specific type of silver consisting of bright, iridescent, sharp, spinel-twinned, "Herringbone"-style silver crystals forming a "fan" or "sail"-shaped specimen. These classic "sails" are part of what makes Batopilas such a great locality. They are immediately distinguished from all other silver specimens around the world.
