In accordance with Seyfried’s stylist Elizabeth Stewart, her costume is Carolina Herrera—however the actual star of the look is the necklace, which Stewart writes on Instagram is a customized design by Catherine Starr of Almasika Positive Jewellery, “that includes De Beers diamonds ethically and sustainably sourced in Botswana.”
The caption continues, “Catherine made this necklace particularly for Amanda as a part of #BlackisBrilliant, a challenge initiated by [De Beers] and [Radvocacy] to amplify Black voices and expertise and provides them truthful illustration on world purple carpets.”
