These specimens are some of the most easily recognizable, dramatic and highly sought after Silver specimens from the Western Hemisphere. This superb specimen is the finest example of this specific type of these specimens that I have handled. It is an outstanding piece filled with bright, sharp, Spinel-law 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. Overall, this is a highly attractive classic Silver specimen from this important Mexican locality.
