Underappreciated point! What makes jewelery a good store of value? Value:volume ratio.

Three trucks full of wet concrete have value too, but they're a helluva lot less convenient to bring with you in a bag on the run.

Jewelry is (a) small, (b) valuable, (c) widely exchangeable for currency or goods.

Sure, you're going to take a haircut on the price, depending on how screwed up your immediate environment is, but there will be some buyers at some non-zero price.
