This is a Vintage Navajo American Era Sterling Silver Bar Pin with Spiny Oyster, Turquoise, and Lapis Lazuli. The pin is marked sterling silver. The stones are a silver inlay mosaic with spiny oyster stones setting the tone. The turquoise and Lapis Lazuli offset the vibrant coral color of the spiny oyster. The entire bar pin mosaic is bordered by a rope twist with a sun motif on either end. The rollover clasp is secure. There is some tarnish/patina; the pin measures slightly more than 2 inches by approximately 1/2 inch wide. Please review the pictures as they are part of the description.
