Just be careful to put some paste or something under it, I said that a couple of years ago to a TSA screener who said she "had to examine my jewelry" (narrow gold chain and small gold earrings) and she grabbed my ring and tugged - luckily I was a little bloated and it didn't come far. I basically haven't worn any jewelry I care about to the US since.
