From Quiz The Hot Rock
Answer: James I
The Sancy probably originated in India, but it's validated history begins in 1570 when it was purchased by Nicholas de Sancy. He loaned it to Henry III of France and Henry IV of France before selling it to James I of England. After that it was briefly owned by Charles I of England. After he was deposed his son, James, fled to France with the diamond, which he was forced to sell. It became part of the French crown jewels, but disappeared during the French revolution. It surfaced again in 1828 when it was offered for sale at an auction, was displayed at the 1867 Paris Exposition and then disappeared again, this time for forty years. In 1906 it was bought by William Astor and the Astor family held it for the next 72 years, before selling it to the Louvre museum, where it still resides.
