Part 2 of Made in Italy large vase

Thanks for replies. I have since read that it would indeed not have "Made in Italy" if it was Murano. I actually wasn't thinking it was Murano, but didn't know what else to look for. I can't find anything that looks remotely like it in all my searching. I just weighed it and it is a whopping 7 lbs 8 ozs, the size of my son when he was born!
I hope someone has an idea who made it or some kind of info about it. I am a research person by nature and it's bugging me that I can't figure this one out. It's probably not very valuable, but I need to solve the mystery. Thanks everyone.
