Prince Charles, the current heir to the British throne, did not wear a diamond crown for his mother's coronation in 1953, as he was only five years old at the time. However, there is a unique diamond crown that is associated with him.
In 1969, a year after his investiture as Prince of Wales, a special diamond crown was commissioned for Charles to wear for ceremonial occasions. The crown was designed by Louis Osman, a British jewelry designer, and was created using diamonds from several royal collections, including Queen Victoria's sapphire and diamond brooch and a diamond necklace that belonged to Queen Alexandra.
The diamond crown features four crosses with fleurs-de-lis at the intersections, with a purple velvet cap and gold braid. The crosses symbolize the four countries of the United Kingdom, while the fleurs-de-lis represent the Prince of Wales's title. The crown is also adorned with several large diamonds, including the Koh-i-Noor, one of the largest diamonds in the world.
The diamond crown was first worn by Charles at his investiture ceremony at Caernarfon Castle in Wales on July 1, 1969. Since then, it has been worn by Charles for other ceremonial occasions, including his wedding to Lady Diana Spencer in 1981 and his mother's Diamond Jubilee celebrations in 2012.
The diamond crown is a unique and significant piece of the British royal regalia, and its association with Prince Charles adds to its historical and cultural significance. As Charles continues to carry out his royal duties and prepares to ascend to the throne, the diamond crown will likely remain an important part of his ceremonial attire.
