On top of the Queen's coffin sits the Imperial State Crown, perhaps the most familiar item

On top of the Queen's coffin sits the Imperial State Crown, perhaps the most familiar item in the Crown Jewels.

The crown sparkles with nearly 3,000 stones - including 2,868 diamonds, 273 pearls, 17 sapphires, 11 emeralds, and five rubies.

Made in the 1937 for the coronation of the Queen's father, King George VI, it was designed to be lighter, and to fit better, than the crown it replaced - which dated back to Queen Victoria.

But nevertheless, the Imperial State Crown still weighs in at a hefty 2.3lbs (1.06kg).
