Vintage Berry Brooch

Vintage Berry Brooch. Orangish red berries on painted green metal brooch. Unknown materials or brand. Berries feel hard and cold, have a little bit of a speckled look, unsure if glass, stone, coral, etc, I really don’t know what they are made of but they don’t feel like plastic or metal. I signed as far as I can see. Color shade varies slightly from photos. Good preowned condition. Pin opens and closes well and has a turning lock mechanism that works. See all photos for measurements and condition.
