Marked, "sterling", this is an exceptionally well done ladies ring that I believe to be Navajo. There is a hallmark inside the band that I can not identify, but I've included close up photos. A raised, silver leaf swirls over the face, between the turquoise stone, and the red coral stone. Harder to find, larger ladies size, size 9. The top is 1&3/4 inches long. PLEASE NOTE THAT THE PHOTOS ARE ENLARGED, TO SHOW DETAIL.
I currently have several pieces of vintage, costume jewelry, and antique jewelry in my shop, including other American Indian pieces, and am happy to combine shipping. To see them all, type the word, "jewelry", or, "Native American jewelry", in the California Girls search box at the top of this page
