Napoleonic or Franco-German commemorative origin - Mystery

An intriguing little mystery from the 19th century—this finely made gilt-bronze star features a brilliant green enamel tablet at its center, bearing a gilt “N” on one side and an ornate “F” on the reverse. At just an inch across, its craftsmanship is remarkable, suggesting that it once adorned a uniform or watch chain as a miniature badge of honor or loyalty. The meaning behind the monograms, however, remains uncertain. Could the “N” stand for Napoleon, linking it to the many privately commissioned commemoratives that flourished during the French Imperial revival? Or might it represent a German noble initial, given the distinctly Continental style of its eight-pointed rays and gilt finish—features seen in 19th-century house orders from small German principalities?

We lean toward a Napoleonic or Franco-German commemorative origin, but welcome insights from our fellow collectors. The dual initials “N” and “F” might suggest Napoléon Français, or perhaps an entirely different personal or dynastic connection. Its lack of hallmarks and miniature size add to the intrigue—clearly a private or presentation piece, but for whom, and by whose hand?

What do you think—French Imperial keepsake, German princely jewel, or something else entirely?
