Vintage Purple Square RIVOLI and AB Rhinestone BROOCH Foil newest Backed Inverted Rivoli Stones Rhodium Plated Heliotrope Orchid Iridescent Stones

Striking brooch set with iridescent purple square rivoli stones surrounded by small AB rhinestones in rhodium plated setting. Some call this color Heliotrope.
I was told this gorgeous brooch was a D & E or a Juliana but has not been verified.
It is an unsigned beauty and a beauty it is!
Measuring 2" by 2", it is in excellent vintage condition.
Great for the holidays. A perfect gift for the brooch newest lover or collector.
