The Briolette of India is a legendary diamond of 90.38 carats, which, if the fables about it are true, may be the oldest diamond on record, perhaps older than the Koh-I-Noor Diamond. In the 12th century, Eleanor of Aquitaine, the first Queen of France and later England, brought the stone to England. Her son, Richard the Lionhearted, is said to have taken it on the Third Crusade.
It next appeared in the 16th century when Henry II of France gave it to his blonde mistress, Diane de Poitiers. It was shown in one of many portraits of her while at Fontainebleau.
After disappearing for four centuries, the stone surfaced again in 1950 when the jeweler, Harry Winston, of New York, bought it from an Indian Maharajah. It was sold to Mrs. I.W. Killam and bought back by Mr. Winston, following her death, about 10 years later.
In 1970, Mr. Winston showed the stone at the Diamond Dinner for American Fashion Editors.
