The Duchess' open collar dress elegantly displayed her diamond and sapphire necklace, which the royal significantly wore for the first time back in 2020 to meet Ukrainian President Volodymyr Zelenskyy.
It's not confirmed whether the Duchess deliberately chose to rewear her necklace in a mark of solidarity with Ukraine, though it's not unlike Kate to style jewellery that contains a hidden meaning or subtle nod of appreciation.

Kate's jewellery bore significance to Ukraine
Many royal fans have suggested her choice to wear blue, a colour within the Ukrainian flag, was also a subtle nod in support of the country given the devastating conflict currently happening in Ukraine.
The Duke and Duchess of Cambridge paid an emotional visit to the Ukrainian Cultural Centre in London last week amid the ongoing crisis.
William and Kate met with members of the Ukrainian community and volunteers and heard first-hand about how the social club is supporting the most vulnerable.
