Do you know that the British crown jewels, the one Queen Elizabeth II wore on her coronation, include the massive Cullinan Diamond, a chunk of the biggest ever gem-quality rough diamond ever found. It was discovered in 1905 and weighed 3,106.75 carats, which translates to 621.35g in weight. The magnificent solid gold frame makes it a very heavy and tiring crown to wear, even briefly, as it weighs 2.23kg (nearly 5lbs). 

This solid gold crown was originally made for the coronation of Charles II to replace the medieval crown melted down in 1649. This original crown was thought to date back to the 11th-century saint-king Edward the Confessor. Back in 1911, St Edward’s Crown was permanently set with semi-precious stones for the coronation of George V.
