Lady Gaga stunned on the 2019 Oscars red carpet as she posed for pictures wearing a black Alexander McQueen gown and Tiffany & Co's legendary 128-carat yellow diamond, which hasn't been worn since Audrey Hepburn over half a century ago.
The Tiffany Diamond is one of the largest yellow diamonds ever discovered and has been owned by Tiffany & Co since 1878. The diamond is known to have been worn by only two women: Mrs. Sheldon Whitehouse in 1957 and Audrey Hepburn in 1961.
