The crown jewels of the British monarch
The crown jewels of the British monarch

Officially, the crown jewels are priceless. They are not insured either, which means they’ve likely never been appraised. However, estimates put the entire collection at almost $6 billion.

At her coronation on June 2, 1953, Queen Elizabeth wore both the St Edward’s crown and the imperial state crown. She carried the sovereign’s sceptre with cross and the sovereign’s orb. Her father, King George VI, also wore the imperial state crown at his coronation in 1937. It was the last time so many of the crown jewels were seen and used at the same time.

The jewelled sword of offering

Created in 1820, the jewelled sword of offering is not as old as some pieces in the crown jewels. King George IV helped design the sword and paid for it at a cost of nearly £6000 or about $956 million in today’s money.

Mary Modena’s crown of state

Originally commissioned as a crown for Mary of Modena, consort of King James II, for his coronation in 1685, this crown of state was made with an array of large diamonds. At the time the crown was made, the value of the diamonds was estimated at £100,650, or about $30 million today.

However, since the crown was last used by Queen Caroline in 1727, the diamonds were replaced with rock crystals.
