Brooch--Unusual Large Art Deco Trembler Faceted Glass Flowers on Wire in Vase

This is a very flashy large 2 & 3/4 by 2 & 1/2 inches brooch and so reflective, I had to turn off the color to scan as it was making rainbows. I believe it is a late 1920s or early 1930s piece--the Art Deco design looks original. No mark and some signs of long life: a couple wires without glass heads and teeny chips on some of the stones. Neither is noticeable. I think it's in good condition except as indicated :)
