Duchess of Cambridge Kate Middleton subtly paid homage to Queen Elizabeth II and Prince Philip on the night of their 70th wedding anniversary, by wearing a family heirloom to the couple’s private family dinner held at Windsor Castle.

The mom of two, 35, was photographed at the property on Monday, November 20, with husband Prince William and brother-in-law Prince Harry. For the formal evening occasion, Middleton selected a black lace Diane von Furstenberg dress, which she thoughtfully accessorized with the Queen’s four-string pearl necklace that features an intricate clasp design.

The piece, first worn by the monarch and family matriarch in the ‘80s, was commissioned after Japan gifted the Queen with a collection of cultured pearls. The late Princess Diana borrowed the necklace for a state dinner in 1982, and it was only natural for Middleton to implement the accessory into her wardrobe on the evening of the Queen’s platinum anniversary to Prince Philip.

The couple publicly commemorated the occasion by sharing photos from their portrait session. According to People, family members and only very close friends—including the Queen’s remaining bridesmaids Princess Alexandra and Lady Pamela Hicks—attended the intimate anniversary dinner. It’s unknown whether Prince Harry’s girlfriend Meghan Markle was present for the affair.
