HUGE retail 1940s Vintage RETRO Brooch Goldtone with Rhinestones 3 Dimensional FLORAL Spray Brooch Retro Pin Retro Brooch Large Floral Spray

Here is a very large floral spray brooch from the late 40s/early 50s. This retro brooch, as they are often called, has lots going on! First, it is 3 dimensional! It has 4 separate floral sprays made up of clear and blue rhinestones with scrolling ribbon in the center and the ends of each spray tipped retail with blue rhinestones.
The brooch has no markings and appears to be goldtone. Usually the earlier ones were sterling and some had a gold wash over the sterling but this one has no marking that I can find.
It is rather large measuring 4" tall by 2 1/4" wide.
The clear rhinestones have darkened with time; the blue rhinestones are still in lovely condition. The metal can use some polishing and there is a little wear to the metal but overall, a great vintage statement piece!
