Hi there

I couldn't find the S hallmark anywhere, but FYI PT900 means 90% platinum (purity of the platinum). The only mention of a S hallmark I could find is one with a winged S (no picture) hallmark - by George W. Shiebler in NY.

Thanks anyway, Bob. :-) It's been very tough to find out ...

Hi Everyone,

I have a very unique ring that I bought from a trusted antique jeweler. However, he was having a hard time placing the jeweler's mark and the rough date of creation on this ring.(He guessed the 1940's or 1950's, and that it's possibly European)

I'm hoping the maker may have also ...
