3 PC Jewelry Set Pearl Ring Necklace and Earrings

Fashion jewelry. I received this as a gift and have not worn it. The ring is too small for me, but not sure what size it is. Post earrings and 17.5 inch necklace with 1 3/4 inch extension making it 19 1/2 inches. See pics. If you have questions, please ask. Smoke free, pet friendly home. Thanks for looking.
