Ring slightly big-platinum bar?

[reds]

I do not want to resize my new ring because my size changes in winter and summer. But right now it turns sideways and I have used the little bar inside my rings before. My question is do they come in platinum and will it hurt my platinum ring. Thanks Reds

Platinum will not be harmed by a sizing spring or much else, for that matter. Don't be too concerned other than having any work done by someone you trust.

Like Dave said ... a sizing spring can help without harm.

DON"T use one of those cheap wrap around sizer thingamabob.

It WILL gouge your ring regardless of metal.
