Stefano Canturi Diamond Barbie, $302,500

Barbie is really America’s most favorite of all its dolls, and really, she’s popular everywhere. So when Australian jewelry designer, Stefano Canturi, decided to sell her wearing one of his beautiful creations, people couldn’t believe what kind of money she fetched. Considering she was wearing a gorgeous black evening gown paired with a choker necklace containing a square-cut, one-carat pink diamond surrounded by other tiny diamonds, she sold for $302,500, making it the most money anyone has spent on a Barbie ever. If it makes you feel any better, the proceeds from her sale went straight to breast cancer research, thankfully.
