Vintage Navajo Sterling Turquoise Earrings. These turquoise drops are simply hallmarked sterling on the back of the screw back finding. The drops measure .5'' by five eighths of an inch with the bail. The silver work is beautiful and holds the turquoise in a saw tooth bezel above a twisted rope border. They could easily be removed from the screw back findings and added to pierced ear wires. There is a line in one of the turquoise cabochons which I believe to be a crack rather than an inclusion. They really are lovely with nice patina.
