The Most Expensive Academy Awards Jewelry in History

2. Anne Hathaway at the 83rd Academy Awards

As you probably know, Anne Hathaway co-hosted the 2011 Oscars with fellow actor James Franco. Such an occasion deserved a memorable piece of jewelry, so, for her first of many looks of the night, Hathaway chose a $10 million Tiffany & Co. necklace. The 94-carat diamond piece was an accessory to her Valentino red carpet gown.
