Vintage Rainbow Rhinestone Teardrop Brooch, ?Juliana

A gorgeous iridescent rhinestone brooch in a teardrop shape. It features three larger baguette rhinestones surrounded by smaller round rhinestones. It’s in excellent condition and unsigned, and could be Juliana but I am unsure. Regardless it’s a truly beautiful vintage brooch with a rainbow iridescent quality. The safety pin is in perfect working condition. 1 3/4” x 1 1/4”, please see video for its full beauty!
