Mexican schorl specimens of this sharpness and quality are rare. A 3.0 x 3.0 cm, sharp, highly lustrous and striated, jet-black schorl crystal surrounded by smaller crystals dominates this very fine specimen from an uncommon Mexican locale - Santa Cruz in Sonora. For the size it is a well balanced piece. Also, it shows none of the etching or solution effects which typically mar the luster on such specimens. As proof of how good it is, it was in, and has labels from, the Dr. Fred Pough (curator, Smithsonian), Dr. Gene Meieran (noted tourmaline collector) and Evan Jones (specialist in Mexico) Collections.
