Handsome vintage brooch signed Industria Argentina

I wish I could find out more about the midcentury maker Industria Argentina. The pieces I've found online have a distinctive flair - they are substantial but also graceful, something like a strong ballerina :). This blooming trio brooch measures about 2-1/2" X 2-3/4". Marked on the back Industria Argentina, Made in Argentina and the initials C.Y.F., presumably the designer. In very good vintage condition, with some darkening of the finish on the recessed part of the back.
