All The Details On Lady GaGa's MASSIVE $30 Million Tiffany & Co. Oscars Necklace!

Lady GaGa was all glamour on the Oscars red carpet on Sunday in an Alexander McQueen dress and jaw-dropping Tiffany & Co. earrings and necklace.

Impossible to miss, the iconic canary yellow Tiffany diamond was the center stone of her blingy pendant, clocking in at 128.54 carats and worth an estimated $30 million. But the starlet isn’t the only Oscar winner to have worn the stunning stone.

The center diamond was last worn by Audrey Hepburn in promotional photos for the 1962 movie Breakfast At Tiffanys, making it was very fitting to be worn by the Best Original Song winner Sunday night.

Eagle-eyed Twitter users were also quick to point out that the Shallow singer’s jewels looked like one worn by another blonde beauty, Kate Hudson, in How To Lose A Guy In 10 Days:

Twitter never lets us down! And neither did GaGa!

Congrats on the win!!
