Vintage Yellow Rhinestone Cornicopia Gold Brooch

I cannot stress enough how gorgeous these yellow Aurora borealis rhinestones are! I can't say I've ever seen rhinestones with this color hue before. They are vibrant yellow, on the verge of chartreuse, with gorgeous rainbow Aurora borealis effects. All stoned are intact. I'm not sure if they are glass or not. The rest of the brooch is gold toned woven metal, in the shape of a cornucopia. The brooch is not huge but it's not small, and it does have quite a bit of weight to it. Truly stunning!
