The Real Reasons Why Queen Elizabeth's Diamonds Are So Precious

The iconic headpiece was made in 1937 for the coronation of George VI, and reduced in height for that of his daughter the Queen. It contains 2,868 diamonds, 17 sapphires, 11 emeralds and 269 pearls, but the most impressive feature is the 317.4 carat Cullinan II diamond - the second largest cut from the original stone - which sits in the crown's band.
