The Sancy diamond is 55.23 carat (11.05 grams) of pale yellow diamond that once was famous as the belonging of the Great Moguls. It’s believed that the diamond is Indian origin. This is the first large diamonds to be cut with symmetrical facets. The stone is also unusual because it has no pavilion – just a pair of crowns, one on the other. This historical diamond is now kept in the French Crown Jewel collection housed at the Louvre.
