"The World's Most Expensive Barbie" has been sold at auction for a whopping $302,500, according to a press release from Christie's, which had the doll up for sale.

And no, you can't play with it, kid.

Created by fine jewelry designer Stefano Canturi, the pricey Barbie boasts a strapless LBD, pink peep-toe pumps, and a Canturi Jewels collar necklace featuring a one-carat Fancy Vivid pink diamond and three carats of white diamonds (a gift from Ken, perhaps?).

Inspired by Breast Cancer Awareness Month, Canturi spent four weeks designing every detail of the luxury lady.

The designer will also donate 100% of the profits -- courtesy of the lucky bidder, a private collector from Asia -- to The Breast Cancer Research Foundation.

Aw. What a doll!
