I don’t have any rose gold Cartier pieces (all my Cartier stuff is in YG) but when it comes to the LOVE bracelet, if you wear it everyday, it’s going to get scratched up (even if you are super careful). There is honestly no way to keep the bracelet pristine unless you either a) don’t wear it or b) wear a sweatband over it all the time but then you can’t see it and getting it would be pointless.
I don’t fully baby my Cartier pieces and when I knock it on things by accident, my heart does break a little (depending on how bad the scratch/dent is) but ultimately you should just get it and enjoy it - don’t worry about the scratches. It’s such a lovely piece and after almost 10 years with my LOVE bracelet, I still love it and have no regrets buying it. Best money I ever spent as it brings me so much joy
