I prefer not to wear my geekiness around my neck, but I quite like this reversible Super Mario Brothers necklace ($12) because it celebrates one of my all-time favorite video game characters. Mario is captured in a clear high-gloss resin and you have the choice of a leather cord or ball chain. I probably wouldn't wear it as jewelry, but I'm sure I could find something to fasten it to.

I wouldn't wear it but I still love it. I could also find a way to fasten it to something other than a necklace.
