Large Sterling Filigree Brooch

This is one of my latest purchases. It looked really sad when I first got it and it is still in desperate need of a bit more cleaning. The brooch is marked only with “925” but I think it is a vintage item. I have a few filigree pieces but generally they are not my favorite kind of jewelry. I liked this one because, although it is rather detailed, it still shows some simple lines.

Thanks for looking:)
