I’d say it’s a brooch for sure, can see the hinge that held the pin on one side and the latch on the other. Nice find!
Yes very nice indeed. Well done.
Yes it's a cherub brooch. Art Nouveau style. Could be late 1800s to early 1900s. Looks too old but still in good shape to be a modern piece, but not certain.
It also looks like a silver color. I would be cleaning the back thoroughly and searching for any markings.
I’d say 1857 or there about
