Beautiful Vintage Prong Aurora borealis rhinestone Unsigned Brooch STUNNING

This is an amazing little brooch that reflects all kinds of shades of light with its multicolor aurora borealis colored rhinestones. Stunning in person. Good quality. Vintage. Rare piece, I didn't any exactly like it when I was looking. I don't know who makes this piece, as I got it at an estate sale, and don't know much about it. It looks like an older piece though. It will probably shine up brilliantly with a gentle clean.
