Mystery Jewel: Scimitar Brooch

Sword pin

Here’s a puzzling brooch. It is in the shape of a scimitar, which makes me think that it might have some kind of Masonic symbolism. It has old, c-clasp hardware on the back, but its simple, flat design seems much more modern. And it looks, smells, tastes and feels like gold but it is unmarked. I’ve spent some time researching it but have come up with nothing. Anybody got any clues?
