This brooch has been in my collection for about 20 to 25 years. A couple tiny stones missing, slight wear on enamel and gold tone silver tone at dangle loop. I have never been able to identify it and I hope someone will help me with it. I would just like to know it is so well-made such fine work that I’ve always thought that it was Marcel Boucher, but it is not signed so be aware of that it is just very wonderful. Has somewhere where the dangling birdcage holds the jump ring but it’s that’s because it’s been worn and it has dangled around quite a lot.
