An 18K yellow gold medallion pendant or charm depicting Emperor Napoleon I. The design pictures Bonaparte as a young man, but the source appears to be Nicolas-Toussaint Charlet's portrait created in 1821, the year of the former Emperor's death. This image is largely credited with creating the myth of Napoleon that lasted throughout the 19th century. The medallion has superb, sharp detail shown in high relief...

The back retains the original watch hook and pinstem...
