Nearly all the best ludlamite specimens come from the Americas: the Blackbird Mine in Idaho, several localities in Bolivia, and the San Antonio Mine at Santa Eulalia, Mexico. This beautiful cluster from Santa Eulalia exhibits glassy luster and good translucence, with a eye-pleasing apple green color. The crystals reach 1 cm in length and are arranged in an unusually elegant cluster, making for a superb thumbnail with both aesthetics and significance for its size class. Almost certainly from a few small finds in the early 1980s.
