The Imperial State Crown (1937)
Includes the Black Prince's Ruby and Star of Africa diamond

Worn by the monarch at the end of the coronation ceremony, and annually at the State Opening of Parliament, this superb crown is virtually priceless because of its major stones, famous either for their historical interest or their actual value.

A sapphire set in the Maltese Cross at the top of the crown is said to have been taken from a ring found on the finger of Edward the Confessor when he was re-interred at Westminster Abbey by Henry II in 1163.

Among the many other gems are included the huge Black Prince’s Ruby, below which is set the Second Star of Africa diamond (317 cts) cut from the Cullinan Diamond. The crown contains over 2800 other precious gems and pearls.
