The modern version of the Imperial State Crown is of a design somewhat similar to that of St Edward's Crown, but shorter and encrusted with jewels: it includes a base of four crosses alternating with four fleurs-de-lis, above which are four half-arches surmounted by a cross. Inside is a purple velvet cap with an ermine border. The Imperial State Crown includes many precious gems, including 2,868 diamonds, 273 pearls, 17 sapphires, 11 emeralds, and 5 rubies.
