It is against the royal constitution for monarchs to take any of the royal regalia out of the country. The ban probably coming into effect to prevent many monarchs from selling or pawning the Crown Jewels when they need the money. Charles I for example sold a great deal of jewels at the start of the civil war to raise the funds in order to pay for his troops. As a consequence when George V, as emperor of India, attended the Delhi Durbar in 1911 to receive the homage of the Indian princes, a new crown was required. It was supplied by the present Crown Jewellers and the cost of £60,000 was met by the India Office. The Crown is one of the heaviest in the collection (weighing 34.5oz) and is set with emeralds, rubies, sapphires and some 6,100 diamonds. On George V's return to Britain the Crown was added to the collection in the jewel house and has not been worn since.
