Im really particular about my car, how do I stop my wifes diamond rings from scratching the paint around the door handles?

Try opening the car door for your wife to keep your wide from opening up the door herself :) It's a WIN WIN!!

Talk to her. She will understand you if she's even half intelligent. If she doesn't care, either you can adjust how you feel about her, or adjust how you feel about the car. Maybe the best compromise is what a few others suggested, namely the clear plastic protectors. Never let her clean the windows as she will scratch the glass permanently.

Buy her a car assistant to ope door for her or maybe change the locking mechanism to more electronic button keychange system(you know new cars have key unlockers and even car start) that would be a fanstastic edition.Nowdays shops have keychange car starts and unlocks by a simple button.

You can get clear plastic stickers that go round the handles but I don't like the looks of them. Just ask your wife to be careful when opening door or you won't buy her any more diamonds.

It's probably just a matter of how she opens and close the door. Or is the ring really big? Maybe short handle? I can think of why it's happening but it sounds a little unavoidable unless you wanna put something there but that'll seem a bit dumb too.

There are clear paint protection 3M plastic decals that you can put on the vehicle for this purpose. Its the same material that is used for a clear bra no not by women on cars to keep bugs and rocks from damaging the leading edges in front portion of hood, bumper etc.

Get a towbar fitted and make her ride in a box trailer...

Or try replacing the diamonds with clear silicone rubber fakes and await divorce papers.

Trade car or wife in on a different one. Or get extras. How many cars or wives is a troll allowed to have?

Maybe have your wife turn her rings around temporarily so the diamonds are inside her hand.

You could replace her with a different wife who doesn't wear diamond rings.
