When it comes to geeky jewelry, the sky is the limit. From funky tetris necklaces [1] to the Lego [2] rings, which I loved and everyone else seems to hate, there really is something for everyone.

This Lego Obsession Necklace [3], $10, was made out of Legos brand flat blocks in black, white, light grey and dark grey. Apparently, if you like this necklace but would like different colors the maker is willing to personalize it for you.
