Gold-plated Hoop Earrings. Approx 1.5”

Gold-plated 1.5” Hoop Earrings. I believe these are gold-plated over sterling silver, but I’m not sure. The number on the posts is “AV925TH” (see pic). Snap closure. I think I purchased these from Nordstrom Rack several years ago. Only wore a couple of times. Great condition.
