At Tuesday's State Banquet for the visiting Japanese royals, Queen Camilla debuted King Charles' family order, a portrait of the monarch traditionally worn by female members of the royal family.
The tradition dates back to the 1820s in the time of King George IV, and usually these were made out of ivory. However, given the King's ecological credentials, the material used was instead polymin, a synthetic translucent treated plastic sheet. The stunning portrait, which sees the King dressed in military uniform alongside his medals was designed by Elizabeth Meek.
The diamonds that surrounded the portrait were taken from the Royal Collection and weigh 10.41 carats. Meanwhile, the blue ribbon was designed by the Queen's favourite milliner, Philip Treacy. Camilla was the only female royal in attendance to wear the new family order, but as their creation is a time-consuming process, it is likely other female royals will wear their own at future events.
However, this isn't the first family order to not be made out of ivory. When the Princess of Wales received her own from the late Queen, it was also made out of a separate material, noting Prince William's own conservation work.

Speaking about the state visit, HELLO!'s Royal Editor, Emily Nash, noted: "The royal family are rolling out the red carpet for the Emperor and Empress and their delegation and it's a really important display of soft power.

"Sending the Prince of Wales to escort the Emperor and Empress to the parade ground further shows how important their visit is considered by the UK government."

A Palace spokesman said this week's programme had been "slightly adapted", adding: "As a general principle, it has of course been adapted as a result of the current pre-election period of sensitivity."
