Tall Art Glass Footed Vase

Picked this vase up at an estate today and I have not been able to find anything like it online. Thought someone may have an idea as to where is was made. From the quality I am guessing Italian glass but not sure. There are no markings on the vase and no label.
It weighs almost 4 lbs It is 12 1/2" tall X 8" diameter at top and 5 1/2" diameter at base.
I would love to know more about this vase.
