I have the same problem that Nick has with rings, so I'm obviously more of a bracelet person. It's quite a shame, really. Rings are incredibly beautiful and stylish, but no matter what, I cannot seem to find one that fits my finger. I don't know if it's because I crack my knuckles or if it's just the way my hands are shaped, but it's disheartening.
Bracelets are awesome, though. My school is in the animal bracelet fad, so I wear those everyday. I also have a sand-dollar bracelet that I wear for good luck, since you make a wish when you put it on.
