When wearing these 'Pentagon' earrings from Adriana Orsini, you really need a hulking great man in a dinner jacket to walk a few paces behind you, primed to beat up anyone who goes near your jewels. At $150 these bits of bling may cost a few million less than the jewels Beyonce and co borrow for big events, but they look surprisingly similar. And by that I mean people will know you didn't get them from Claire's!
