Stunning multi stone SS dangling earrings

I fell in love with these earrings a few years ago but, sadly, have never had a chance to wear them. I am ready to let them go now.. the colours are stunning, and will complement many outfits 2.25" long the top square stone is just over 0.5" wide and is the most intense blue the second down is an aquamarine the marquise is an amethyst and the last, smallest stone is something greenish blue, not sure what type of stone
