Aunt Sabina's Brooches

The silver leaf brooch is a Trifari and one I wear often. For a brooch that has no "bling," I find it very attractive. The red brooch is all "bling" and the one I think of as my fireworks brooch. It's not one I wear often, just doesn't seem to be as versatile as the silver one. I inherited both when my aunt passed away. Can anyone tell me about the red brooch? Date? Manufacturer? I always photograph the backs but often forget to include a common object for size reference. The red brooch is about 2-1/4" across.
