ITSNONAME is the office of Brooklyn-based (by way of Minneapolis) husband-and-wife designers, Joe Johnson and Jeanju Choi-Johnson (as quoted by their website). I think these Periodic Rings are pretty dope. These Rings run like this :

Ag Silver Periodic Ring: $205.00 USD
Au Gold Periodic Ring: $2,350.00 USD
Pt Platinum Periodic Ring: $6,600.00 USD

Some other science inspired jewelry designers also caught my eye. Sarah McLellan and Kristina Ortega created a jewelry line called Mctega in which they use mass production techniques of industrial chemistry on a much smaller scale to create some fabulously unique pieces. These girls come from a science background and are hoping to cross over from jewelry to clothes. These necklaces run from about 100-350 bucks.
