This piece uses turquoise from the Turquoise Mountain mine in Arizona. The pale blue waterweb and light brown matrix create a very beautiful work. The back is stamped "sterling." Generally, Navajo jewelry is stamped "sterling" instead of "925." This is recommended for those who want authenticity or are looking for a natural stone pendant in Indian jewelry. Please check the images and consider purchasing. There are no noticeable scratches, and I think it's in very good condition. INDIAN JEWELRY NAVAJO Turquoise Mountain Arizona Arizona
