FWIW, I lost my wedding ring while traveling, less than 4 months after I started wearing it. It really is the sentimental value, especially since the design we picked for me would be very hard to replace (jeweler went out of business, and their supplier had already dropped the design from their catalog by the time we ordered it).
More recently, DW's heirloom wedding band lost a pavé stone. We found the stone and her mom is having it repaired.
For now, we're both wearing cheap silicone rings, and plan to continue that as our day-to-day option. I just wish I'd thought of that while I still had the original ring to wear on special occasions, etc.
