Antique womens brooch ???

Antique women's brooch

Found at 1800's homesite. Copper or brass? Has flower motif on it. I am assuming this is a woman's brooch, although I don't know anything about women's jewelry. What was in the middle - cameo, imitation jewel? With the bar at the top, would this have been tied with a ribbon around the neck, or maybe in the hair??

Any ideas or opinions? Thanks for looking.

I think it's a suspender clip.

Two piece buckle, tongue portion is missing.

Thinking out loud...Not quite like the suspender clips I recall seeing here, and a togue of the right size wouldn't fit through the wreath. Similar to both of these ideas though.
What about part of a book lock or latch... Like old diaries or bibles might have had, with a closure strap?
