I'm a fan of geek jewelry, especially, when designers break out of the usual mold of electronics shop class basics strung on wire, but I don't think I've yet seen a piece that I would truly want to wear. It's a little hard to tell from a photo (it looks delicate but it's not shown on a finger), but I think I'd wear this wooden sweet resistor ring, made from eco-friendly salvaged wood, and a hand-painted wood "resistor" bead. The Chicago jewelry designer, who is identified only as "craftsman" studied at the Art Institute of Chicago and was inspired by watching his father work in his metalworking studio. Craftsman can customize the resistor ring or make unique, hand-etched wedding rings and even wooden-banded diamond solitaire engagement rings.

"I handcraft every ring to bring out the warmth and honesty of the wood. Each ring is hand formed from thin layers of wood chosen for its grain and durability. learning how to make a wooden rings has been a rewarding process of discovery which for me continues to this day. I have learned that the wood which is chosen carries more than just its physical traits but more than that the wood carries deeper spiritual meaning."

As a bonus, wearing wooden jewelry means superstituous types always have something to knock on. The resistor ring is $24, but the whole shop is worth a look through. Craftman's store is part of a cool new site I just found out about, called Etsy, that lets you buy and sell handmade items. The geekery category is full of some pretty inspired bits of techno creativity.

Thanks to Nicole, for pointing out the site and the seller!
