This brooch was from Francois Kramer, circa 1855. It was originally designed as an old mine and old Europeancut diamond openwork sculpted bow. Napoleon III had it made for his wife, Empress Eugenie. Henri Loyrette, the President of Louvre, arranged a private sale with Christies New York in order to bring this piece of historical jewelry back to its homeland of France on April 22, 2008.
