I wish I had bought a titanium ring. I had no idea at the time I chose my gold band but apparrently I'm hard on rings.
I can definitely sympathise here. I bought a 9ct gold ring. I've been married less than a month and the damn thing is already scratched to hell and back. It's not like I do handyman work or anything like that, the most strenuous thing I do with my hands is type on a keyboard.
