Queen Camilla will be crowned alongside King Charles III on May 6.

She'll wear Queen Mary's 1911 coronation crown, which has 2,200 diamonds.

This is the first time in recent history that an existing crown will be used for the coronation of a Queen Consort.

The late Queen Elizabeth II's Cullinan III, IV, and V diamonds will be added to the crown.

Four of the crown's eight detachable arches will be removed to create a different impression.

King Charles will wear the historic and traditional St. Edward's Crown.

The Koh-i-Nûr diamond was moved from Queen Mary's crown to Queen Elizabeth II's mother's.

There will be no debates over where the Koh-i-Nûr diamond came from or calls for it to be returned to India if it is not used.

The St. Edward's Crown has recently been updated and is now available for public viewing.
