Kate Middleton 'Replaced' Her Sapphire Engagement Ring to Resemble Her 'Love and Commitment' to Prince William

Kate Middleton has been seen with a new eternity band instead of her signature sapphire ring — which once belonged to Princess Diana — which could symbolize her close bond with Prince William.

Diana first picked the accessory out of a catalog, and William proposed to Kate with the historic item back in 2010.

"This looks to resemble the promise ring that Prince William gave Kate at university when they first started dating; this was a rose-gold Victorian band embellished with pearls and garnets: representing both their birthstones," Citron-Thompkins explained.

"It is not the first time that the infamous Princess Diana ring has been missing during an outing, and it could simply be that it is being cleaned or resized, and Princess Kate has used the eternity rings in its place to help disperse any rumors," she continued.

According to the professional, Kate's new marital token paid "the perfect homage to the ring it replaced."

During the early stages of Kate's medical leave, conspiracy theories spread online about the state of the Waleses' union, as Stephen Colbert joked about William's alleged relationship with Rose Hanbury.

"I’m afraid I’ve got some troubling news about England’s royal family,” Colbert said on the March 12 episode of his late-night show. “Internet sleuths are guessing that Kate’s absence may be related to her husband, and the future King of England, William, having an affair.”

"I think we all know who the alleged other woman is, say it with me, The Marchioness of Cholmondeley,” Colbert continued. “Now there have been rumors of an affair between William and [Hanbury] since 2019. According to tabloids, back then, when Kate supposedly confronted him about it, he ‘laughed it off, saying there was nothing to it.’ Aha, always a good response when your wife accuses you of cheating."

The Marchioness of Cholmondeley's legal team quickly shut down the claims, telling an outlet: “The rumors are completely false."

OK! previously reported royal experts believe the future queen's cancer battle strengthened her bond with William.

“Her focus is on her husband, her children and getting strong enough for a very gradual return to work," royal correspondent Jennie Bond stressed. "I think her illness has made her marriage to William stronger than ever, and that was evident from the video."

“You can try playing peacemaker for just so long, and it looks as though she did make some attempt to bridge the gap," Bond continued.

Throughout her cancer battle, William juggled caring for her and The Crown.

"The cancer journey is complex, scary and unpredictable for everyone, especially those closest to you," the mom-of-three continued. "With humility, it also brings you face to face with your own vulnerabilities in a way you have never considered before, and with that, a new perspective on everything."

"This time has above all reminded William and me to reflect and be grateful for the simple yet important things in life, which so many of us often take for granted. Of simply loving and being loved," the future queen said. "Doing what I can to stay cancer-free is now my focus."
