She donned a black Alexander McQueen gown with sheer sleeves and floral embroidery. The look was completed with lab-grown diamonds from Atelier Swarovski.
Olivia's statement jewels included a pair of floral earrings with dangling drop and rings made with responsibly sourced white gold. One ring featured lab-grown sapphires, white diamonds and pink diamonds. The other style was a show-stopping floral ring featuring a 2.03-carat cushion cut, purple-pink, lab-grown diamond.
The difference between the lab-grown diamonds and traditionally mined stones is the former are made with "less environmental and adverse human impact," according to Atelier Swarovski. The stones still share the same physical, chemical and optical properties, states the brand's website. They are both made from 100 per cent carbon with the same hardness and brilliance.
The lab-grown jewellery beautifully brought out the glinting embroidery on Olivia's dress. Combined with her rosy natural makeup and cropped hairdo, it made for a gorgeous finish.
The actress also accessorized with an ERA (Equal Representation for Actresses) 50:50 ring. She previously wore the important piece of jewellery to the 2020 Golden Globes. ERA 50:50 is a British organization that wants gender balance on screen and stage in the UK. According to ERA's website, the organization was started after a report revealed male actors are overrepresented in Britain by a ratio of 2:1.
Olivia certainly wasn't the only celebrity to embrace the suggestion of trying to make more sustainable choices on the red carpet. Duchess Kate rewore an opulent gold and white gown by Alexander McQueen to the 2020 BAFTAs.
The Duchess of Cambridge first wore the detailed dress on her tour of Malaysia with Prince William in 2012. Eight years since she debuted the gown, it still had tremendous impact. On this occasion, the duchess accessorized the frock with a sparkling gold clutch, Jimmy Choo heels and a necklace and earring set from Van Cleef & Arpels.
