Actually, there is a worry - you could get robbed, or held at gunpoint and be forced to hand over your jewelry. Sure, the crooks will not the least suspect that your ring is actually a hardware wallet storing thousands of dollars worth of crypto (but then again, why are you carrying it on your hand everywhere in the first place?), but it will be, at best, a hassle to recover your coins, and, at worst, a crypto theft.
I am not a fan of the idea either. But hey, you don't have to wear it all the time like your wedding ring. Put it on when you intend to use it and take it off when you are back home. Not all jewelry that people wear is valuable. Some people wear friendship bracelets or bracelets their kids made for them. It's not worth a cent and may look bad, but had sentimental value.
