Native American Silver Turquoise Cuff Links

Older Native American cuff links of silver with bezel set large turquoise nuggets, which have probably been stabilized or treated. Metal may be sterling on the top only, we are calling it silver tone metal as we aren't sure and no markings. It is fairly rare to find good old Native American cuff links at all. Each cuff link measures 1" at the largest point and both are in good condition.
