Toenail, 2.8 x 2.7 x 1.0 cm
Himalaya Mine, San Diego County, California, USA

While the Himalaya Mine is most noted for tourmalines, on occasion the mine has given up rarities like this incredibly sharp and textbook-crystallized, tabular columbite. The crystal is doubly terminated, has good luster and exhibits a dark battleship gray color. From the private collection of Herb Obodda, this is an important San Diego County specimen for the mine.
