Is King Charles' friendship bracelet a gift from Princess Charlotte? Monarch wears accessory in Guernsey - days after his granddaughter sported a matching one to Wimbledon

From his gold signet ring engraved with the Prince of Wales crest to his impressive array of watches, the King has an enviable range of jewellery - and it appears he's added to his collection.

Charles, 75, has been spotted wearing what appears to be a 'friendship bracelet' during recent engagements, including today for his visit to Guernsey with Queen Camilla .

Made up of yellow and red thread, the band seems to be similar to versions sported by His Majesty's granddaughter, Princess Charlotte , nine, when she attended the Wimbledon final over the weekend with her mother, the Princess of Wales .

Dressed in a navy polka dot frock, Charlotte wore two of the threaded bracelets, one featuring various shades of pink and another boasting green, blue and pink fabric.

It's unclear if the King's new jewellery piece is a gift from his granddaughter. MailOnline has contacted Buckingham Palace for comment.

The King was also pictured wearing the bracelet yesterday when in Jersey with Queen Camilla, as well as during his visit to the Senedd in Cardiff to mark its 25th anniversary on July 11.

Alongside his colourful bracelet today, the monarch wore a grey suit teamed with a purple shirt and patterned tie as he stepped out in Guernsey for the second day of his visit to the Channel Islands.

He was joined by Queen Camilla, who sported a bandage on her right ankle today. Aides said she has suffered an ‘slight ankle sprain’ while on neighbouring Jersey - where the heavens opened for the royal visit - yesterday.

The white dressing was clearly visible as she and King Charles arrived in St Peter Port to be greeted by huge crowds and blue skies.

Camilla, 76, sported low heels with a royal blue silk crepe dress and coat by Fiona Clare but appeared to be leaning on an umbrella as she walked.

Despite the apparent minor injury, she looked delighted to be on Guernsey soil this morning, not least because the sun was shining.

The royal couple faced a deluge yesterday in Jersey as their two-day tour of the Channel Islands kicked off in soggy style. It is the first official visit by a monarch to the Channel Islands since 2005, when the late Queen Elizabeth visited Jersey.

While the Queen, who will celebrate her birthday during the royal visit when she turns 77 tomorrow, wore the striking royal blue dress jacket, the King donned a light grey suit, with a blue cornflower on his lapel.

The royal couple were greeted by hundreds of smiling well-wishers as they made their way along St Peter Port seafront to Guernsey Parliament.

In some places, the crowds were five-people deep as they patiently waited to catch a glimpse of their King and Queen.

When they did arrive, the Royal Standard was raised on the Weighbridge Mast and a 21 gun salute fired. They then took part in a special sitting of the States of Deliberation.

It is traditional that a special sitting of the States of Deliberation is held when the Monarch visits Guernsey for the first time and occurred in 1957 for the first visit of Her Majesty Queen Elizabeth II.

The Seigneurs and Dames also paid homage to His Majesty. As he and the Queen took their seats in carved thrones.

Guernsey’s links to the Crown stretch back centuries. The Channel Islands formally became part of the Duchy of Normandy in 933, then Normandy and England came under common rule from 1066 after the victory of William the Conqueror at the Battle of Hastings.

After 1204, Guernsey pledged to remain loyal to King John of England when he lost his continental Normandy territory to the French King.

And now, 820 years on, the Channel Islands are the only part of the former Duchy of Normandy which remains loyal to the British Crown.

Later, the couple spent time chatting to those who'd turned out to see them before heading to the Crown Pier in Saint Peter Port for a showcase of Guernsey culture, including heritage, produce and environmental initiatives.

Clearly enjoying the prospect of some refreshment, King Charles picked up a pint of local ale.

The Monarch then took a sniff to enjoy the beer's aromas before enjoying a sip.
