Hitting the gym. Wearing your ring during cardio activities won’t do it any harm, but it’s the weight lifting that can take a toll. The pressure of the weight’s bars (or really, any amount of strong pressure) that’s applied to your band might bend it, which is especially bad for a pavé band because the smaller stones can fall right out of their setting. As for contact sports, definitely take off the ring, or risk a serious injury thanks to ring avulsion.
When you do take the ring off, don’t just leave it anywhere willy nilly. Keep it in a box or jewelry pouch separate from your other baubles (so it doesn’t scratch them).
Just remember, however, while these dress codes provide guidance as to what each style of dress means, that definition looks to the past and is shaped according to what the dress codes used to mean.
