The Prince and Princess of Wales were present at the royal wedding of Crown Prince Hussein and Princess Rajwa in June.
At the Jordan royal wedding, the Princess of Wales surprised everyone with a stunning tiara.
She wore the Lover's Knot tiara, adorned with diamonds and pearls, which was frequently worn by her late mother-in-law, Diana, Princess of Wales.
The last time she wore this sparkling headpiece was at the State Banquet for South Africa's President Cyril Ramaphosa in November.
In addition, a month later, she wore the Lotus Flower Tiara at the Diplomatic Corps reception at Buckingham Palace.
It remains to be seen when the Princess will wear these jewels again.
There is a possibility of a US state visit in the coming months, as President Joe Biden met with King Charles at Windsor Castle on Monday.
White House spokeswoman press secretary Karine Jean-Pierre confirmed that Mr. Biden had accepted an invitation from the King, which was extended during a phone call in April.
During the conversation, she mentioned that the President extended his congratulations to the King on his upcoming coronation.
They had a friendly discussion, indicating a positive relationship between them.
The President reminisced about his pleasant visit to Windsor in 2021 with the First Lady and expressed his desire to visit again soon.
Interestingly, during the call, the King offered the President a state visit, which the President gladly accepted.
It is evident that they have a strong bond and share common concerns, values, and important issues such as climate change.
The discussion on these matters will continue during their upcoming visit in the near future.
She mentioned that she doesn't have a specific timeframe and cannot predict when the visit will take place, but she stated that the President appreciated the King's offer and is eagerly anticipating it.
The Buckingham Palace spokeswoman declined to provide any further information regarding the arrangement.
The tea meeting at Windsor Castle on Monday was not an official state visit, which typically involves a military guard of honor and a formal white-tie state banquet attended by senior members of the royal family.
During state banquets, the annual Diplomatic Corps reception, and the State Opening of Parliament, it is customary for the royal ladies to wear tiaras. Therefore, it is likely that Princess Kate and Queen Camilla might have an opportunity for a tiara moment in the near future.
The friendly and warm relationship between King Charles and President Biden was evident as they inspected a Guard of Honor in the Quadrangle at Windsor Castle. They were photographed shaking hands, and later, the US leader was seen placing his hand on the monarch's back.
The King and the President's most recent encounter took place on the day before the funeral of the late Queen Elizabeth II in September. A reception was organized for dignitaries as a prelude to the national event.
The visit to Windsor was just one of the many engagements for Mr. Biden during a busy day. He made a brief stopover in London en route to the NATO summit in Vilnius, Lithuania.
