Vintage sterling turquoise foliage/ leaf studs

Cute little vintage Native American/ southwestern stud earrings made of sterling silver and turquoise colored stones-Im not sure if they're real turquoise but pretty nonetheless. Stamped sterling on the back and signed with the maker's mark. Intricate silverwork with foliage/leaves. Will sanitize and supply with sterling backings with purchase. Measures about 1/3" wide and 1/2" long.
