Vintage Mexican Parrot Hoop Earrings 2"

These are umarked silver hoop earrings and I will presume they are Alpaca and not list as sterling and price accordingly. I don't know how to definitively test for sterling but you may find out they are after purchase as I can see hammering on the hoops. The earrings are in excellent condition. They measure 2" x 1 1/2" and are in wonderful condition, no flaws. These were made in Mexico.
