Yes, sound advice. My jewlery was all from one guy in reddit whose brother owns q jewlery store so he prices to move and tests. I test all my stuff too with scratch test.

Jewlery you can bring across borders without confiscation like you said. People, remember it was illegal to own gold bullion for a while, under FDR I believe. It was confiscated. I also brought my whole collection to woo a girl during a romantic boating date and we capsized and I lost it all.

I only have the memories that I try to live vicariously through because I haven't come to terns with my loss

Also my state charges tax on bullion but there are places you can get from that avoid it. Pm me if you are affected and want some pointers.
