Vintage Navajo Turquoise & Sterling Earrings

Purchased on the Reservation 20+ years ago. Made by a Navajo Artisan. These are pierced posts. I haven’t worn them in a while so they could use a cleaning w silver polish. (The last pic posted is a snapshot of duplicate earrings for sale on a competitor site that I posted for information only. Various Navajo artisans make/made this earring. They are ALL listed as Sterling with authentic Turquoise, ranging for resale anywhere from $50 to $239) I think $50 is reasonable.
