This is from someone who doesn't really wear her stuff, in part because she has been burned by poor workmanship: IT IS SAD. I have been making a very concerted effort not to loupe it as often and so far so good, then again, I havent been wearing them much either. In part due to the fact that it's friggin cold out and I don't do rings with gloves. Scratches in the metal like you're talking about are gonna be there even when you haven't worn it because there's simply no such thing as pure smooth "unscratched" metal, really. The metal is polished with fine grit and rouge and a chamois. That is gonna leave, what looks to you under a loupe, like little teeny tiny scratches. Im not sure if this will help but look at those little scratches as love. You love the ring and you're wearing it. Its a hell of a lot cheaper to get a setting replated, repolished and remade if need be, than it is to replace a diamond.
