This adjustable silver tone Genius Calculator Ring is just what you need to prove to that stubborn boss of your that you deserve that raise on top of a holiday bonus!

Go ahead & flaunt that bling bling, nerd-style.  I think I may have to reorganize my gift list & add this baby to the top!  Now, if only the calculator really worked & the buttons were diamonds…  Cost, $8
