Hi everyone! My dad gave me a lovely David Yurman ring, silver, yellow gold with a blue topaz. The thing is, it's one size too big. I don't want to get it resized (I'm lazy, I know)... where do they sell those rubber thingies you can put on a ring (the part facing your palm). Do you know what I mean? Or is there some homemade thing I can do myself? Thanks. Hope this isn't a stupid question.
