(She's) So Heavy Lead Crystal Vase

Behold this small, but might vase. The pictures don't do it justice. This vase weighs a little over 4 pounds. The height is 4 3/8" and the width is about 5 1/4." The opening in the top is merely an 1 and a hakf.The piece has an Orrefors-esque feel but is unsigned. I see one or two tiny air bubbles, which tells me that this is probably not Orrefors. If you have seen this bowl before and know where it is from, I'd love to know.
