This was not a "blink and you'll miss it" moment. No, Lady Gaga went big with her Oscars look [1], wearing the 128.54-carat, cushion-cut "Tiffany Diamond" necklace as the scene-stealing complement to her black Alexander McQueen gown. The necklace, which features one of the largest yellow diamonds in the world, has only been worn three times since its discovery in 1877 — most notably worn by Audrey Hepburn in promotional photos for Breakfast At Tiffany's in 1961.

Apart from the jaw-dropping 128.54-carat Fancy Yellow diamond sitting front and centre, the necklace is set in platinum with 16 cushion-cut diamonds and 46 round brilliant diamonds. It's safe to say that the singer and actress, who is nominated for best actress and best original song [2] for A Star Is Born, chose a statement piece worthy of the evening.

Reed Krakoff, Tiffany & Co. Chief Artistic Officer, agreed — sharing that he was "thrilled that she will be wearing the legendary Tiffany Diamond on the awards show red carpet for the first time since it was discovered 141 years ago."
