Circuit Board Necklaces

Circut Board Necklaces ($20). Not only do these look incredibly cool, but by wearing one, you're saving the world. Seriously. In fact, printed circuit boards make up three-percent of electronic landfill waste—waste that definitely does not return to the earth as it sits. These necklaces take some of that would-be waste and turn it into a totally unique diamond or circular circuit-board pendant. Fun and functional.
