Dear Gaspare, I'm pretty sure You will be able to say more when I will post more detailed pictures of the skull ring. If I got burned this will hurt not much because paid not too big money :-). This one came from a good source but sometime s***t happens.
As for Polish ring the markings these are typical proof markings for silver. It is a lady head with number 925 and letter B for city Bydgoszcz where the ring was proofed. The secound marking this are initial of the manufacturer WS I guess.
