Sterling Silver Turquoise Inlay Screw Back Earrings

Sterling silver screw back earrings that are inlay set with pale blue Dry Creek Mine turquoise. 

They have been repaired or changed to a screw back as there are solder and file marks on the back that blur the "sterling" mark. 

Measure 7/8" long x 1/2" wide. Total weight: 6 grams. Well made. Possible Navajo.
