Not a Poli piece, as it is not really colors he worked with, and, more importantly, his designs were more architectural in feel. Elegant simplicity with well defined forms. The look of the green, and it not being UV reactive would lead me to conclude it is a little newer piece, as in 1970's or newer.
Italian Sommerso glass seems to have become to Seguso and Flavio Poli as it seems all two colored (Tango) Czech glass has become to Loetz and Michael Powolny. An internet myth that may never die!
