Native American Navajo Sterling Silver Turquoise Studs - Pierced Earrings

Dating to the 1970s/1980s or so, here's a pair of Sterling Silver (tested, not marked) stud earrings design in a Native American Navajo manner. For pierced ears, the findings are posts with mismatched nuts (hallmarked 925). Fronts measure 3/4" x 1/2" approx. and feature serrated cut cabs of turquoise. Combined weight of the pair is 3.4 grams. Beautiful true LEFT and RIGHT pieces with no problems I can spot - just maybe a little polishing needed to take off some tarnish.
