Jackie's Emerald and Pearl Brooch
Composed of emeralds and pearls. Reportedly nicknamed the "Russian Brooch." Jackie had it in her collection prior to becoming First Lady. There is photographic evidence of her wearing the brooch at one of the 1960 Presidential debates. The brooch may have been a gift from JFK or the Kennedy family (with the emeralds highlighting the Kennedy's Irish heritage).
