These Periodic Rings from ITSNONAME (wtf?) are available in silver, gold, and platinum. Each features the corresponding metal's atomic number and weight and come in sizes 7, 8 and 9. Silver will set you back a paltry $205, gold (14K yellow) a staggering $2,200, and the platinum a holy shitting $6,500. Now I can think of a lot better ways to blow $6,500, and none of them include periodic table themed jewelry. Although one does include a drive across country with a one-legged hooker and a trunk full of drugs. Wait, that was a movie idea. No, no it wasn't. That is how I'd spend $6,500.
Two more pictures after the jump, including one of what it'd look like to get punched.
