These Mid Century goldtone fiery aurora borealis rhinestone clip earrings could represent comets, shooting stars, or maybe even cats (smile). They have double curved rows of prong set small AB stones with a larger rhinestone at the base, or head if you prefer. Length is about 1-1/8 inch. The backs are unsigned. The iridescent stones of course tend to reflect any nearby colors, including the blue curtains in the room where I took the pictures.
