Old Lion's Head Ring - Ornate & Beautiful NEEDS WORK

Unusual old lion's head ring. The ring is split in the back. I think t used to be a stone in its mouth (now missing). The eyes are made of some type of polished red stone or glass. It is 5/8" wide at its widest point and is 1/8" wide at the back. I don't know the exact size, I estimate it to be size 8 or larger. I do not know the age or history of this ring. I think it is made of brass, but I don't know for sure. If you have any questions, please feel free to email me. Thanks for looking !
