Congratulations on your engagement! Personally, I love wearing my engagement and wedding rings, but never wear them when riding or running, since my hands swell and they get uncomfortable. I never wear earrings, either, since my helmet straps always seem to grab them. All the sparkly stuff is insured, so it stays home. You might check with your insurance company about a rider for your homeowner's policy to covery your jewelry. It's not expensive, and if something does happen, you'll be able to replace it.
