These earrings remind me of the green curtain from the Wizard of Oz.  They are truly ethereal and have a glow to them under certain light.  Please see all pictures.   These iridescent, ribbed oval glass caboshons are approximately 3/4 of an inch long.  They are secured  in a beautiful copper colored brass prong oval setting and are dangling from copper toned (nickel-free) French style ear wires.   The total length of the earrings is approximately 1  inch.
