Does anyone have a clue as to who might have made this beautiful crystal art glass piece? This goodie has been suggested as being made by Iitalia, Finland but the ones found are not like this one on the base above the bubble. Their pieces slope upwards whereas this one is flat on the bottom of the carafe or vase. It is 9.5" tall and holds one quart of liquid. It is a heavy piece weighing in at two and a half pounds Any input is greatly appreciated.
