Gorgeous vintage filigree flower brooch

This brooch is stamped 900. It’s vintage and I don’t know a lot about it. It’s beautiful and delicate. The only flaw is on the tip of one of the petals it’s bent. I would have taken a photo but bending this piece is what caused the tear in the first place. I couldn’t tell which one it was and felt it best to not try bending every petal to find it.
