Gold Bracelet, Lucerne Bell Marked 750 & Fleur de lis?

[NFLgirl]

This bracelet is marked on the clasp with 750 and a Fleur de lis (Fleur de lys). It certainly has the look and feel of gold, and the 750 hallmark for 18K but I can't seem to find the combination of gold and the Fleur de lis hallmark. Any ideas or information? I know it doesn't look like 750 from the picture (it was hard to get a clear picture that close) but under a jewelers loupe you can see it is definitely the 750 mark.
