Sorry everyone for the heading..I had no idea how to describe this vase. Got the flu so I'm a bit fuzzy in the brain

I'm hoping the pics will tell the story.
Under the flash the vase goes very white, but you can see in the pics without the flash that it isnt. The edge of the rim is very sharp, almost razor sharp. This is not the type of glass I usually buy but I just found it very beautiful. I've taken a shot also facing into the vase to try and show the mottling effect. (Probably wrong word I know)
I'd love to know who made this...
