Orders of Saint George made by jewelers Louis Duval and Jean-Pierre Ador

The very first crosses of the Order of St. George were commissioned to the jewelers Louis Duval /Луи Дюваль/ and Jean-Pierre Ador /Жан-Пьер Адор/. By the end of 1769 Louis Duval had made 20 “large crosses of the military order” (i.e. crosses of 1st/2nd class) at 22 rubles each and 50 “small” ones (i.e. crosses of 3rd/4th class) at 18 rubles. Jean-Pierre Ador made 30 large crosses and 50 small ones. In December 1770 jeweler Duval were paid “1250 rubles for making one hundred crosses of the Order of the Holy Great Martyr George and seven cavalier stars”.

Between 1769 and 1806 only 42 "large crosses" of 1st and 2nd class were awarded. Currently three "large crosses" are known that almost certainly were manufactured by above mentioned jewelers.
