Barbie with diamond necklace going to NY auction

Barbie with diamond necklace going to NY auction - The curvaceous, custom-designed doll wears a necklace featuring a one-carat, purplish-pink diamond. She's being offered at Christie's auction house in New York on Oct. 20 for an estimated $300,000 to $500,000. Christie's says that would make her the world's most expensive Barbie.

All proceeds will benefit The Breast Cancer Research Foundation in support of Breast Cancer Awareness Month.

Jeweler Stefano Canturi arranged the emerald-cut, fancy vivid diamond in a geometric pattern with smaller, white diamonds, totaling three carats. He also designed the doll's black strapless party dress, stilettos, hair and other features.

The world auction record for a Barbie is $17,091, set in 2006 at Christie's London. ( Associated Press )
