Stunning Pendant and Necklace Set featuring Genuine Crow Springs Turquoise set in Sterling Silver Pendant. 18" Sterling Silver Bead Necklace is included. Created by Navajo Artist Sampson Jake. Signed by the artist. The Crow Springs Mine is located near Tonopah, Nevada. The Crow Springs Turquoise Mine was closed for many years. It recently was opened by Dennis and Lucy Cordova. The Smith family previously owned the mine. This family had been mining turquoise in Nevada since the 1870’s. In 1909, William Petry discovered a deposit one mile southwest of the Crow Springs claim. In 1939, Ann Cooper Hewitt, heiress to the Cooper Hewitt fortune, made from inventing the mercury-vapor lamp and the first fluorescent lighting, filed claim to the mine and built a home there, which she called AnnJax. She did little work on the property and subsequently abandoned it.
