Kate wears Princess Diana emerald choker during Earthshot Awards

Catherine, Princess of Wales, delighted at the 2022 Earthshot Prize awards Friday evening, showcasing her sustainable style in a rented gown and accessorizing with an emerald choker once popularly worn by her late mother-in-law, Diana.

The emerald and diamond, art deco-style choker was a firm favourite of the late Diana, Princess of Wales, who daringly once put on it across her forehead as a headband during the entourage of Australia in 1985 with her then-husband Prince Charles. Queen Elizabeth II had loaned her the piece of jewellery.

Kate paired the choker with a vibrant green off-the-shoulder Solace London gown rented for £74 ($90) from online platform HURR for the grand finale of a three-day royal trip to the US.

The event staged this year in Boston was one of the highlights of the Prince of Wales’ calendar and had been dubbed the future King’s “World Cup” moment by Hannah Jones, the prize’s chief executive officer.

Speaking during the ceremony, William said: “I believe that the Earthshot solutions you have seen this evening prove we can overcome our planet’s greatest challenges. And by supporting and scaling them we can change our future.

“Alongside tonight’s winners and finalists, and those to be discovered over the years to come, it’s my hope the Earthshot legacy will continue to grow, helping our communities and our planet to thrive.”
