Stunning vintage enamel and glass moonstone cornucopia pin, circa 1930s. It looks like Coro or Trifari and there are marks on the back, but hard to read. There is a hand engraved number on the back: C245-229-83. It tests silver and is very heavy. Measures 2.5" by 2" and in very good vintage condition. I could not find another like it on the internet.
