Beautifully etched vintage earrings in sterling silver

These classic button-shaped screw back earrings have fine details and virtually no tarnish, so look decades younger than their years. They were designed by the Forstner Chain Corporation, which was founded in the US 100 years ago and specialized in fine jewelry made of gold and silver. They are about 3/4 inch in diameter. Marked Sterling Silver and FCC on the screw backs, which are in great working order.
