The individual objects symbolise different aspects of the service and responsibilities of the monarch.
Charles will be presented with the Sovereign's Orb, the Sovereign's Sceptre with Cross, and the Sovereign's Sceptre with Dove and other items at key moments in the ceremony.
And Camilla will be presented with the Queen Consort's Rod with Dove and the Queen Consort's Sceptre with Cross - mirroring the King's sceptres.

Reporting inside Westminster Abbey
The King and queen consort will shortly take their places before the high altar of the Abbey.
It’s a place known as the Coronation Theatre which gives a sense of this being the focal point for the drama and tradition we’re about to witness.
We’re going to see the King presented to the congregation, symbolically turning to the four points of the compass, he’ll be given a Bible and then we’ll hear the oaths, which this time will be framed by a recognition of people having their own “faiths and beliefs”.
For the anointing he’ll step forward to the rather battered but beautiful, 700-year-old Coronation Chair.
This is placed in the middle of the painstakingly-restored medieval Cosmati pavement, which was in such a bad state it was covered up with carpet for the previous Coronation.
It was made by 13th-Century Italian craftsmen with many of the pieces of mosaic believed to have been salvaged by medieval bargain-hunters, who took material from old ancient Roman ruins.
So King Charles will be crowned on top of fragments of an even older civilisation.
"I come not to be served but to serve," says the King as Westminster Abbey falls silent.
