Art Nouveau iridescent glass vase

Can anyone please identify this vase for me. I am assuming it is Art Nouveau. It appears to be blown, iridescent green glass, cylindrical, with a bulbous foot and is 10 1/4" high and 5 1/4" wide at the widest part. I think the metal-swagged rim is copper since there is green patina on the underside. There is no signature or mark. Thank you
