Vintage Navajo Indian Sterling/Turquoise Earrings

Simple, bohemian style. Earrings were purchased at a Navajo Trading Post in the early '70's & have been in my collection for 35 years. 925 Hallmark around studs loop is worn but jeweler tested as Sterling Silver. The silver is beautifully patina'd, getting better with each year. Earrings are set with 4 cabochon cut turquoise stones set next to a silver bar dangling from a pierced stud with 3 more stones. Turquoise are a bright turquoise blue.
