In addition to St. Edward's Crown, the Imperial State Crown and the Queen Mary Crown — these are the royal family's other crowns.

King Charles III will wear two crowns — St. Edward's Crown and the State Imperial Crown — on coronation day, May 6, 2023, while Queen Camilla will wear Queen Mary's crown with one major change.

The crown on the coffin, as Town & Country pointed out, is the Imperial State Crown, which is “made of gold and set with 2,868 diamonds, 17 sapphires, 11 emeralds, 269 pearls, and 4 rubies ...

The Queen only wore the second crown once ... As of 2019, the value of the jewels and gold used in the making of St Edward's Crown was estimated to be more than £3.6million.
