Oh yours is really pretty too!  It looks to be in really great shape.  Mine is very worn compared to yours.  I know both my grandmother and her aunt wore it  a lot

I agree about not replating.  Both of my vintage pieces are non-plated as well.  I know my local jeweler that specializes in pieces like this won't replate when work is done unless you specifically ask for it.

I do have a 10K ring from 1920 is a bit more yellow but I like the look of it.  This ring is only slightly yellow but very pretty.  I think it adds to the look!
