The Regent Diamond is a diamond owned by the French state and on display in the Louvre, worth £48,000,000. It is widely considered the most beautiful and the purest diamond in the world.
In a letter to his London agent dated 6November 1701, Thomas Pitt, the Governor of Fort St. George, writes:
"... This accompanies the model of a Stone I have lately seene; it weighs Mang. 303 and carrtts 426. It is of an excellent christaline water without any fowles, only att one end in the flat part there is one or two little flaws which will come out in cutting, they lying on the surface of the Stone, the price they ask for it is prodigious being two hundred thousand pag. tho I believe less than one would buy it"
Pitt claimed he acquired the diamond from the eminent Indian diamond merchant Jamchund for 48,000 pagodas in the same year, so it is sometimes also known as the Pitt Diamond. He dispatched the stone to London hidden in the heel of his son Robert's shoe aboard the East IndiamanLoyal Cooke, which left Madras on 9October 1702. It was later cut in London by the diamond cutter Harris, between 1704 and 1706. The cutting took two years and cost about £5,000 Rumours circulated that Pitt had fraudulently acquired the diamond, leading satirist Alexander Pope to pen the following lines in his Moral Essays
"Asleep and naked as an INDIAN lay
An honest factor stole a gem away;
He pledged it to the Knight, the Knight had wit,
So kept the diamond, and the rogue was bit."
Pitt bought the diamond for £20,400, and had it cut into a cushion brilliant.
Sale to the French Regent
After many attempts to sell it to various Members of European royalty, including Louis XIV of France, it was purchased by the French Regent, Philippe II, Duke of Orléans, in 1717 for £135,000, at the urging of his close friend and famed memoirist Louis de Rouvroy, duc de Saint-Simon. The stone was set into the crown of Louis XV for his coronation in 1722 and then into a new crown for the coronation of Louis XVI in 1775. It was also used to adorn a hat belonging to Marie Antoinette. In 1791, its appraised value was £480,000. In 1792, during the revolutionary furore in Paris, "Le Régent", or the regent diamond, was stolen along with other crown jewels of France, but was later recovered. It was found in some roof timbers in an attic in Paris. The diamond was used as security on several occasions by the Directoire and later the Consulat to finance the military expenses: 1797-1798 it was pledged to the Berlin Entrepreneur Sigmund Otto Joseph von Treskow and 1798-1801 to the Dutch Banker Vandenberg in Amsterdam. In 1801 the gem was permanently redeemed by Napoleon Bonaparte. by François Gérard. Note the Regent Diamond set in the Fleur-de-lis at the top of the crown. Napoleon used it for the pommel of his sword, designed by the goldsmiths Odiot, Boutet and Marie-Etienne Nitot. In 1812 it appeared on the Emperor's two-edged sword, which was a work of Nitot. Napoleon's second wife, Archduchess Marie Louise of Austria, carried the Régent back to Austria upon his exile. Later her father returned it to the French Crown Jewels. The diamond was mounted successively on the crowns of Louis XVIII, Charles X and Napoleon III. Today, mounted in a Greek diadem designed for Empress Eugenie, it remains in the French Royal Treasury at the Louvre. It has been on display there since 1887. Experts have estimated the Regent Diamond value to be near £48,000,000. At the current 2016 exchange rate of $1.28 USD / £1, the Regent Diamond value is estimated at $61,440,000 USD.
Folklore
Due to numerous scandals, and the misfortune of those who have been in possession of the stone, the Regent Diamond is said to be cursed.
