Famous Yellow Diamonds
The Allnat diamond mysteriously appeared after 1950 when Major Allnat commissioned Cartier to fashion a setting for the 102.7 carat yellow diamond. It was auctioned in 1996 as a ring and sold for over 3 million dollars. The stone was re-cut to 101.29 carats which increased its color and clarity, increasing its value. The Allnat diamond is currently on display at the Splendor of Diamonds collection at the Smithsonian Museum.
The Sancy diamond weighs 100 carats and has passed through many hands throughout history. In 1389 the diamond was part of Valentina’s dowry. Valentina married Charles VI of France’s brother, the Duke d’Orleans. Over the succeeding years the diamond was in and out of pawn, being used as collateral until the Duke John of Burgandy seized the diamond as a spoil of war. The diamond was passed down through his family until Charles the Bold, thinking the diamond was good luck, brought the diamond with him into battle. Charles was killed in the war and the diamond disappeared for 14 years. The diamond reappeared when John Fugger sold the diamond to the King of Portugal. The diamond remained in Portugal until Phillip II of Spain invaded Portugal. Even though Phillip ii claimed the Sarcy Diamond as a spoil of war, the king escaped with the jewel. The King of Portugal sold the diamond to the Elizabeth I of England. She secretly pawned the diamond to finance the war against Spain. The diamond was bought by Nicolas Harlay de Sancy for his wife. Elizabeth I eventually bought the diamond back when Sancy went bankrupt. The diamond was pawned severeal times until 1660 when Cardinal Mazarin purchased the jewel. When Cardinal Mazarin passed away, he willed the Sancy Diamond to the French Crown. The diamond became a part of Marie Antoinette’s collection, until her death when it disappeared again. The diamond ended up with the Spanish Crown until it was reclaimed by Joseph Bonaparte. The stone disappeared for 25 years and was then purchased by Nicholas Demidov, who gave it to his wife. The diamond passed to Jamsetee Jeejeebhov and then in 1865 to William Astor. The diamond remained with the Astor family until 1976, when they sold it to the Louvre Museum, where it remain today.
