Queen Camilla was a vision in blue as she stepped out in Rome today to kickstart her four-day state visit with King Charles in Italy. The Queen dazzled as she arrived at the Quirinale Palace, the Italian president's official residence, for the official welcome.

Camilla wore a stunning blue silk crepe dress and coat by Fiona Clare, which she paired with colour-matching blue heels and a beige handbag. For the special event, the Queen donned a diamond and sapphire brooch that was once Queen Victoria’s, as well as Queen Elizabeth's. The brooch, known as the Prince Albert brooch is estimated by experts to cost around £8million due to its sentimental value.

Prince Albert's brooch commissioned Garrards to make the brooch in 1840 for his bride-to-be, Victoria.

He gave her the brooch on the night of their wedding. The stunning piece was frequently worn by Victoria before it was passed down to Queen Elizabeth II, who also donned it on several occasions.

The brooch is said to have inspired the Princess of Wales's iconic engagement ring, which was first given to the late Princess Diana by King Charles.

Max Stone, of jewellers Steven Stone, said: "The [brooch] contains a large oval or cushion-shaped sapphire, which is at least 40cts.

"The breathtaking gem is also surrounded by 12 large diamonds, which look to be around 12cts.

"Due to the clarity and intense colour of the sapphire it was possible sourced from Burma. If it was to be sold today, it would be worth around £8,000,000, thanks to its historic legacy."

During the first full day of the King and Queen's tour, they recieved a ceremonial greeting and watched a joint flypast over the capital by the Italian Air Force's aerobatic team, Frecce Tricolori, and the RAF's Red Arrows.

The president and the King then held a private meeting while the statesman's daughter, who acts as the first lady, showed the Queen a selection of antique books on horsemanship in the Biblioteca del Piffetti and toured the staterooms.
