Vintage Luigi Briglia big artisan clip on earrings

Amazing vintage statement earrings. Made by Italian jewelry designer Luigi Briglia. Unique and rare piece of jewelry! Each earring is missing one stone. I think it would look nice with a hematite stone/bead but a rhinestone would be nice too. I have pictured it with a small bead and stone that’s not included they are just to show the idea of replacing it with something. Or leave it as it is. Please see photos for the best description thank you.
