Well, the most collectable of these 1960s-style glasses was made designed by Wiktor Berndt for Flygfors, but there seem to have been many factories copying the idea. The Flygfors pieces are very high quality with a beaten copper effect and all signed, so yours probably isn't that.
Yours seems to be higher quality than the vase of blue glass with an iron sleeve which is discussed in this thread here
, and tentatively identified as being Spanish, possibly Lafiore.
There seem to have been a lot of people copying the idea. For instance, I have one piece with the label of an Australian factory which I think was called Leona Glass (and yes I should know, but almost everything we own is in storage at the moment including all my notes & glass.)
