Princess Kate made a surprise appearance in a new video released Sunday celebrating the achievements of Team Great Britain at the Paris 2024 Olympics. And following the release of the clip, fans quickly noticed something particularly interesting about the Princess of Wales’s outfit: her eternity band.

In place of her engagement ring, Kate wore a gold band encrusted with white diamonds and sapphires—a perfect and more casual alternative to the royal’s iconic sapphire-and-diamond engagement ring from Prince William, which once belonged to his late mother, Princess Diana.

The new band also resembles the promise ring William gave Kate when they first started dating as college students at the University of St. Andrews in Scotland. That piece was a rose gold Victorian band embellished with garnets and pearls—the first being Kate’s birthstone, and the second William’s.

It isn’t clear when Kate got her lovely eternity band, but some fans believe it may have been a present from William to mark their 13th wedding anniversary, which fell on April 29, as this is the first we are seeing of the piece.

In the video, Kate wears the band with a white and black striped top from Ralph Lauren. William, next to her, wears a light blue Team Great Britain polo shirt (and some new scruff). “From all of us watching at home, congratulations to Team GB,” Kate says. “Well done on all you have achieved,” William adds, addressing the athletes. “You’ve been an inspiration to us all.”

Kate’s rare appearance in the video comes as she continues her preventative treatment for cancer. The princess revealed her diagnosis back in March via an emotional video statement in which she wore a striped top very similar to the one she wore in the new clip, and which was shared on Kensington Palace’s social media accounts.
