Possibly 1920's Jewelry?

Found this in a house I was demoing. (Built in 1922)
I don't know much at all about this. Any input would be greatly appreciated. Thanks

It's an old "backing earring" as I know them lol my Grama used to wear those sometimes.
They slide on your ear lobe, and the backing she tightened, to stay in place.

Hope it helps
