Hello Leebo60, welcome to GD.C!
If there is one thing you should NEVER do to an SSring, and I emphasize NEVER, it is to clean it....

Ring looks worn, with some small wearing damages (but still HIGHLY collectible!) and original to me, as far we can see from these pictures.

The ring was obviously the death head ring of Herbert Siemß, 1938/39 at staff of Abt.XII, at these times no party member, his SSnumber has been 277348 and he was born on 6.2.1912. He became SSleader (Ustf) on 12,9.1939.
