The State Crown of George I is the imperial and state crown crafted in 1714 for King George I. It was modified and used by subsequent monarchs until 1838. The empty gold frame and its aquamarine monde which dates from the reign of King James II are both part of the Crown Jewels of the United Kingdom. They are on public display in the Martin Tower at the Tower of London.
