My rings only cost $100 over 30 years ago. Not pricey, but never thought about taking them off.
It's an interesting subject to bring up, though. One of my daughters has a set worth over $10k. They are insured, but I still may make the suggestion to her to leave them home next time. I did tell her DH to not even think about putting them on her finger unless they were insured, as she loses stuff nearly every single day. Thankfully, he had them insured at the jeweler when he purchased.
