3/$15 ⭐️ Vtg cuff links wrap style gold tone brown agate stone cufflinks (B)

These cuff links are in great condition gold tone with brown agate stone. There is a makers stamp on reverse but I can’t make it out clearly I think it’s an S so perhaps swank. I am selling my cuff link collection and always happy to entertain reasonable offers and love to bundle. Thanks for looking! The letter in () is my cataloging info it has no meaning to the piece.
