People Editorial Guidelines Published on December 7, 2022 11:00 AM Share Tweet Pin Email Meghan Markle is sparkling like Princess Diana. The Duchess of Sussex, 41, slipped on her late mother-in-law's aquamarine cocktail ring for the Ripple of Hope Award Gala in New York City on Tuesday evening, where she and Prince Harry received the Robert F. Kennedy Ripple of Hope Award. The statement piece added a pop of color to Meghan's white off-the-shoulder dress, a look she completed with diamond bar earrings and her hair worn in a slicked-back bun. Meghan famously debuted Princess Diana's aquamarine ring on her wedding day in 2018, giving a wave to photographers as Harry drove to their evening wedding reception in a vintage Jaguar convertible. She reached for the piece again during a royal tour of Tonga later that year, sporting it for a private audience with King Tupou VI and Queen Nanasipau'u.

The piece is valued at $90,000, and Diana previously paired it with a matching aquamarine and pearl bracelet.

The Duchess of Sussex has also been photographed in Diana's butterfly earrings, gold bracelet and diamond tennis bracelet.

Princess Kate, 40, popped in an electric green gown that she sustainably rented for the prize ceremony and delighted royal watchers when she wore Diana's emerald and diamond choker. The statement piece likely hadn't left the royal vault since Princess Diana last wore it in 1997, the year she died. The late royal glittered in the emerald necklace many times between 1981 and 1997, most memorably wearing it as a headband while touring Australia in 1985. It was by accident that Diana came to wear it as a headpiece. Instead of clasping it around her neck, she tried to fit it over her head, but the choker became stuck, according to royal biographer Kitty Kelley. She liked the way it looked across her forehead so much that she decided to wear it that way for the evening.
