Since the first Academy Awards in 1929, the Oscars have been synonymous with cinematic excellence and high-wattage glamour. What began as an intimate dinner at the Hollywood Roosevelt Hotel has evolved into a global spectacle watched by millions. Alongside celebrating achievements in film, the ceremony has become one of the most closely observed showcases for high jewellery, where the world’s leading maisons unveil some of their most extraordinary diamond creations on the red carpet.
Legendary houses such as Cartier, Harry Winston, Tiffany & Co., and Chopard have long adorned Hollywood’s elite with exceptional pieces. Harry Winston, often referred to as the “Jeweller to the Stars”, has been a red-carpet fixture since the 1940s, famously lending diamonds to icons including Elizabeth Taylor and Jennifer Lopez. Tiffany & Co. made modern history when Lady Gaga wore its legendary Tiffany Diamond at the Oscars, while Chopard continues to craft bespoke high jewellery for nominees and presenters each year. Together, these maisons ensure the Oscars remain one of the most influential stages for diamond jewellery.
