We’re off the deep end forLady Gaga‘s Oscars jewelry!
Always one to go above and beyond fashion expectations throughout herA Star Is Bornpress tour, the nominee for Best Actress and Best Song was one of the most anticipated actresses to attendthe Oscarson Sunday. Her teamat the Haus of Gaga previously told PEOPLEthat “there’s a lot more to do” with her elevated, elegant red carpet style, and with this Old Hollywood look, she definitely surpassed many expectations.
Not only did she wear a gorgeous Alexander McQueen gown with matching leather opera gloves, she accessorized it with an incredibly valuable — and historically significant — piece of jewelry, the Tiffany Yellow Diamond.
“Lady Gagais the ultimate creator, innovator and rule breaker, and I’m 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,” Reed Krakoff, Tiffany & Co. Chief Artistic Officer, said in a statement.

Added her Sandra Amador and Tom Eerebout: “The chance to work with such an amazing piece of design and history tonight is a creative dream come true. There are so many beautiful jewels in the world, but the radiant Tiffany Diamond, which weighs over 128 carats, is truly exceptional, which is just so fitting forLady Gaga.”

Tiffany had found it in 1877 and acquired one year later.
In honor of Tiffany’s 175th anniversary in 2012, the one-of-a-kind gem was reset into the eye-catching necklace, which is the style Gaga wore. It features over 100 carats of white diamonds.
Gaga is the first celebrity to wear the Tiffany Diamond since Audrey Hepburn, whofamously wore the massive yellow stonein publicity photos for her famous 1961 filmBreakfast at Tiffany’s.

Socialite Mary Whitehouse was the only other women to wear the piece, debuting it in a lavish necklace at the 1957 Tiffany Ball in Newport, Rhode Island. The Tiffany Diamond has also appeared in the windows of the Fifth Avenue flagship store in New York City.

Gaga’s high-fashion Oscars moment marks the culmination of a busy awards season for the star, who continues to push the envelope with her style.
“I think she’s very diverse with what she wears,” said Tom Eerebout, a longtime member of the Haus of Gaga who co-styles the superstar alongside Sandra Amador, “But the pieces that she wears are very her.”
While the necklace was the focal point of Gaga’s Oscars look, one piece of jewelry from her personal collection was noticeably missing from her left hand — thepink diamond engagement ring from ex fiancé Christian Carino.
The Oscarscomes less than a week after a rep for Gaga, 32, exclusively confirmed to PEOPLE that she andChristian Carino, a talent agent for CAA, haveended their engagement.
Speculation began that the couple had split after eagle-eyed fans noticed that Gaga did not wear her engagement ring to theGrammy Awardson Feb. 10. She also did not thank Carino in her acceptance speech after winning the Grammy for Best Pop Duo or Group Performance for her song “Shallow.”
