These are just absolutely beautiful they’re petite screw in and they do say MFA Sterling that’s the signature on the back. I had them in this beautiful leaded glass box and I thought that they should stay in there since they’re the adorable, beautiful color blue so I’m selling these as a set right along with the Glass box, what a nice gift this would make LOVELY PETIT POINT EARRINGS 💙💙💙💙💙
