Tiffany & Co. has introduced the Empire Diamond Necklace, the most valuable piece ever offered for sale by the iconic jewellery house. The show-stopping centrepiece is an 80-carat, D-colour, internally flawless oval diamond, set in a platinum necklace inspired by a historic Art Deco design.

Valued at over $20 million, the necklace reimagines a piece originally created for the 1939 World’s Fair, which featured a 200-carat aquamarine. The new version replaces it with one of the rarest white diamonds in the world—sourced in Botswana, cut in Israel, and finished at Tiffany’s New York City workshop. Named after the Empire State, the diamond is celebrated for its chemical purity and perfect clarity.

The necklace is adorned with 578 diamonds—including 353 round brilliants and 224 custom-cut baguettes—arranged in a refined Art Deco silhouette. Notably, the centre diamond is removable and can be worn as a ring, enhancing its versatility.

The Empire Diamond Necklace debuted at Tiffany’s Blue Book event in Dubai and quickly garnered global attention. Beyoncé was the first to wear it publicly, including at her 2022 Oscars afterparty and in a British Vogue feature.

While Tiffany’s famous 128.54-carat Tiffany Diamond remains its most iconic (and not for sale), the Empire Diamond Necklace is the first of such calibre to be made available for purchase—solidifying the brand’s position at the pinnacle of luxury and high jewellery design.
