When Are the Crown Jewels Used? The Two State Occasions

The British Crown Jewels are reserved for just two formal state occasions:

1. The annual State Opening of Parliament – The monarch wears the Imperial State Crown and carries the Sovereign's Sceptre and Orb.
2. The Coronation – The full regalia, including St Edward's Crown, is used during the crowning ceremony.

Outside these events, the jewels are kept under guard in the Jewel House at the Tower of London, where they are on public display.
