The rare, 128-carat Tiffany Diamond, made famous by Audrey Hepburn and last worn by Lady Gaga, will appear in the new 20th Century Studios daring mystery-thriller, “Death on the Nile,” based on Agatha Christie’s 1937 novel.

A recreation of The Tiffany Diamond features at the center of the storyline, alongside other Tiffany designs worn throughout the film. “Death on the Nile” stars Tom Bateman, Annette Bening, Kenneth Branagh, Russell Brand, Ali Fazal, Dawn French, Gal Gadot, Armie Hamer, Rose Leslie, Emma Mackey, Sophie Okonedo, Jennifer Saunders, and Letitia Wright.

“The Tiffany Diamond is a priceless symbol of the highest standards of virtuosity and craftsmanship at Tiffany, and rarely makes an appearance beyond its vault,” said Reed Krakoff, chief artistic officer. “A central role in the adaptation of Agatha Christie’s classic novel is deserving of our priceless diamond.”

The Tiffany Diamond, a rare fancy yellow diamond, was unearthed in 1877 as a 287.42-carat rough diamond from the Kimberley mines of South Africa and procured by Charles Lewis Tiffany. In 1878, the rough diamond was cut in Paris into a 128.54-carat cushion-shape brilliant with an unprecedented 82 facets, revealing thes stone’s extraordinary fire and beauty.

This October, Tiffany & Co. will promote the film in stores and across its digital platforms, highlighting Tiffany’s radiant yellow diamonds and the exceptional collections seen on screen. Select Tiffany stores will feature a “Death on the Nile” curation of diamond-intensive Tiffany jewelry reflecting looks from the film, including exquisite and one-of-a-kind high jewelry pieces, Tiffany & Co. Victoria and Schlumberger designs.

In addition, store windows that capture the spirit of Christie’s thrilling mystery and feature jewelry from the film will be featured at the Tiffany Flagship Next Door in New York, the Beverly Hills boutique in Los Angeles, and the Old Bond Street location in London.
