925 Bali Knot Hoop Earrings Sterling Silver

Condition: Preowned. Excellent condition but some mild patina in hoop. May be intentional part of design. Material: the piece that goes through the ear is 925 Sterling silver but I’m not sure if the hoop section is or not. It doesnt appear to be stamped like the other part. Smoke free home. Pet friendly home. Items stored away from pet. No trades. Reasonable offers welcome.
