India’s Isha M. Ambani appeared with her jewellery collection at the Met Gala 2025

Celebrities from around the world showcased their Best Natural Diamond Jewellery at the Met Gala 2025. Isha M. Ambani wore an incredible necklace from her “personal jewellery collection.” Boasting over 481 carats of diamonds, Ambani had the piece made to replicate Cartier’s famed Toussaint Necklace, as seen in the 2018 film Ocean’s 8.

Jacques Cartier designed the original necklace upon which the one created for the film is based in 1931. The Maharaja of Nawanagar was its recipient, and it included what was described as “the finest cascade of coloured diamonds in the world.”
