This pin features a blue diamond believed to have been cleft from the famed stone called "Le Tavernier" - the same stone as the Hope diamond.
The stone, originally set as a ring for Empress Maria Feodorovna, wife of Emperor Paul I, was given to the Diamond Fund in 1860, by her daughter-in-law, the Empress Alexandra Feodorovna.
