Hi Teapot. As I'm sure you're aware, there is no commerce on the playa. Anything you bring, such as jewelry, would be to share or gift. You can decorate the jewelry with the Burning Man logo, and make a really unique gift to offer up at your discretion.
You can do a Google search of the BM logo, and find many variations of it.
Welcome to eplaya and I hope you make yourself at home here!!!
Just because I like to wash myself in public and gnaw on the bars of my cage all night doesn't mean I want to be stuffed up someone's bum. ~~Savannah
