Silvertone Mermaid with Pearl Charm/Pendant

New, Silvertone mermaid. She holds a cage above head that has a Pearl bead inside. This can be changed to any bead that fits inside. Chain closes the Pearl in place securely. Mermaid is very detailed. Unsure of metal. I don’t see a stamp. Metal isn’t magnetic. Unsure of the metal content or brand. Very unique piece.
