Interesting thread!
I wear some combination of mine all the time, except when I shower, wash dishes, clean, etc. I have a solitare engagement ring that I've always had, and I wore a small, plain gold band with it. A year or two later I got a nice wrap for the solitaire, then I decided the smaller band didn't look right, so I got a fat one. Last Christmas I got a diamond band, sometimes I wear it on my right hand, but it's a 1/4 size too big, just enough to slide around and bug me, so if it's on my right hand, I wear the thin band in front of it to hold it on, then I wear the fat band with my solitaire and wrap on my left hand. Depends on my mood I guess.
DH wears his all the time, but I finally convinced him he needs to take it off when he mows the grass or uses the chainsaw, these both make his hands and fingers swell. He's had to have his band cut off 3 times from the chainsaw, one would think he'd learn to take it off first, especially since his hobby was being a paramedic (his certification ran out and no time to take the classes again). The jeweler said they probably can't fix it anymore, he'd have to get a new one. The first time it was swollen so bad before he finally went to get it cut off that his finger was starting to turn blue.
