The Princess of Wales has once again swapped out her engagement ring for her stunning eternity band in a touching new video shared yesterday.
Kate, 42, joined her family in a deeply personal clip, filmed in Norfolk last month, to confirm she will return to public duties following the completion of her chemotherapy course.
Her heartfelt message about her cancer journey is spoken over images showing the Waleses and their children enjoying the outdoors, walking through woods and the couple shown cuddling as they hold hands.
During one emotional moment, as the Princess is heard saying: 'To all those who are continuing their own cancer journey - I remain with you, side by side, hand in hand', the royal is seen walking through a field.
She holds out one of her hands to run her fingers through the tall grass, and showcases her wedding ring and her new 'eternity band', which she appeared to swap out for her engagement ring, that once belonged to her mother-in-law, the late Princess Diana.
After spotting the change in the royal's chosen jewels, royal fans suggested the ring (which Kate also wore in her last appearance) is likely a gift from Prince William - and could be the sign of a 'fresh start' now her chemotherapy has ended.
It isn't the first time Kate has showcased the jewellery - she wore the ring in a star-studded congratulatory message to Team GB following their success at the Paris Olympics.
Appearing alongside the Prince of Wales, the Princess was seen with a new band on her wedding ring finger, leading royal fans to speculate it is an eternity ring.
The thick gold ring appeared to be set with diamonds and sapphires, which would match the royal's engagement ring that once belonged to Princess Diana.
In her heartfelt message yesterday, Kate describes the past nine months since her serious health issues began as 'incredibly tough for us as a family' and how the 'cancer journey is complex, scary and unpredictable for everyone', with the experience giving her a 'new perspective on everything'.
In the video, she says: 'Doing what I can to stay cancer-free is now my focus. Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes.
'I am however looking forward to being back at work and undertaking a few more public engagements in the coming months when I can.
'Despite all that has gone before, I enter this new phase of recovery with a renewed sense of hope and appreciation of life.'
After seeing the clip, and a shot which focused in closely on her hand while she wears the eternity ring, royal fans suggested it was the Princess's way of sending a message to fans and other cancer sufferers.
Taking to X/Twitter, fans speculated that the ring was 'definitely' a gift from Prince William, her husband of 13 years.
Another fan speculated that the eternity ring may be the sign of a 'fresh start' for the Princess, now she has finished her treatment and will mark 'the next phase of her life'.
Kate, who is continuing to work from home, is hoping to return to a light programme of public duties for the remainder of the year, reflecting her need to make a full recovery, and aims for a handful of engagements in the coming months.
She is also working towards appearing with the royal family at the annual Remembrance Sunday service staged at the Cenotaph in Whitehall.
The princess' Christmas Carol concert at Westminster Abbey has become a firm fixture in the royal calendar in recent years and she has begun working with her team on the project.
Kate has received messages of support from the public and said she and her husband had 'drawn strength' from all those helping them and 'Everyone's kindness, empathy and compassion has been truly humbling'.
The video, shot in August in Norfolk where the Waleses have a family home, sounded a positive note reflected in the images of Prince George, Princess Charlotte and Prince Louis playing in fields or enjoying a game of cards with their parents under a tree.
It ended with the princess' words of reassurance for others who are still being treated for cancer: 'To all those who are continuing their own cancer journey - I remain with you, side by side, hand in hand. Out of darkness, can come light, so let that light shine bright.'
Kensington Palace has not confirmed whether the princess expects to return to a full programme of duties next year. It is understood that decisions about 2025 will be taken in line with medical advice.
However sources told the Mail tonight that the Princess hopes to do a small number of engagements shining a light on some of the causes, issues and charities that are closest to her heart over the coming months.
They are only likely to be announced last minute as they will depend as and when Her Royal Highness feels able to carry them out, with sources stressing repeatedly that every ‘cancer journey is different’.
Kate announced publicly five months ago that she had been diagnosed with cancer and has been undergoing 'preventative' chemotherapy.
'I am well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirits,' she said at the time, in a highly emotional and unprecedented video message.
The message followed the major abdominal surgery Kate had in January, where she spent two weeks at the London Clinic in Marylebone.
She made her first public appearance since the bombshell announcement in June when she joined the Royal Family to celebrate the King's official birthday.
Her appearance at Trooping of the Colour had been in doubt after she missed the final rehearsal the weekend prior to the celebration, with confirmation that she would attend only given at 6pm the evening before.
In her second public appearance, the mother-of-three attended Wimbledon alongside her daughter, Princess Charlotte and her sister, Pippa Middleton.
Kate - who enjoys taking part in sporting events and showing her support for athletes - also made a surprise appearance alongside Prince William with a star-studded message to Team GB earlier this month.
