S.A.C vintage pearl earrings caged in gold swirl

S.A.C vintage gorgeous pearl earrings in a gold swirl cage! They have the fabulous screw on backs! These were my grandmother’s! I haven’t been able to take them in for appraisal due to covid, so I’m unsure of exact worth and materials used. I’m just hoping I haven’t underpriced them 🤞😬! Preloved great vintage condition!
