While speaking on stage, alongside fellow cast members Rachel Weisz and Florence Pugh, Johansson flashed her yellow pear-shaped engagement ring, which looks to be set on a thick black band.
Though no details have been released surrounding who designed the piece, British Vogue notes the ring's unique design is similar to that of French designer James de Givenchy, the nephew of Givenchy founder Hubert de Givenchy and the founder of New York-based jewellery label, Taffin.
