Vintage Gray & Aurora Borealis Rhinestone Eye Brooch

Don't miss out on this sparkly vintage domed eye shaped brooch! It has black diamond (gray) rhinestones in both emerald and chaton shapes, as well as smaller aurora borealis rhinestones. It is prong set in silver tone metal and measures 2 1/4" x 1 3/8". It is in excellent condition. It is unsigned and I was unable to find any information on it, so if anyone knows who made it, I'd appreciate knowing!
