Royal Wear! See King Charles in His 2 Crowns on Coronation Day

King Charles donned the St. Edward's Crown and the Imperial State Crown for the historic event

King Charles has officially been crowned — and he had two special ones for the occasion.

Following the death of his mother Queen Elizabeth in September, King Charles became monarch on Sept. 8, however, his historic service was carried on out at Westminster Abbey on May 6.

During the ceremony, King Charles was crowned with the St. Edward's Crown, which weighs nearly 5 lbs and was first created for King Charles II in 1661.

Keeping with tradition, the St. Edward's Crown, which is only used to crown a new king or queen during the coronation ceremony, was last used in 1953 for King Charles' mother, Queen Elizabeth.

At the end of the service, King Charles changed into a separate crown, donning the Imperial State Crown. This particular crown is slightly less heavy at a little over 2 lbs. — but still just as stunning with its 2,868 diamonds and colored stones, including 17 sapphires, 11 emeralds and 269 pearls.

Like the St. Edward's Crown, the Imperial State Crown is also used on ceremonial occasions. It was last seen on Queen Elizabeth's coffin during her funeral in September.

Queen Camilla, whom King Charles named as his Queen Consort in September, was also crowned with a notable headpiece. She wore the Queen Mary's Crown, which was worn by Charles' great-grandmother Queen Mary when she took part in the coronation alongside her husband, King George V, in 1911.

Her crown was a historic moment as it marked the first time in recent history that an existing crown was used for the coronation of a Queen Consort instead of a new commission being made, the palace said, "in the interests of sustainability and efficiency."
