From Avon in the 1970's, this brooch depicts cameo design with a bouquets of flower tied with a ribbon. The flowers are dainty and it's almost Victorian in style.
I'm not sure what the material is that it's made of, could be resin, Lucite or even Thermoset. It's orange in color, almost a dark peach with cream colored flowers and border. It's almost translucent when you hold it to light.
Could it be Bakelite? No idea but you get the idea of the material.
The brooch is approximately 1.5 inches long and 1 inch wide. No damage that I see but please inspect the photos.
