The stone totals 128.54 carats and was first discovered in South Africa over 140 years ago by Tiffany & Co. founder Charles Lewis Tiffany. In honour 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, who wore the massive yellow stone in publicity photos for her 1961 film ‘Breakfast at Tiffany’s.’ The only other woman to sport it was socialite Mary Whitehouse who wore it in a lavish necklace at the 1957 Tiffany Ball in Newport, Rhode Island.

While Gaga wore the historically significant jewel to complete her look, what was noticeably missing was the pink diamond engagement ring from ex-fiancé Christian Carino.
