Topic: Chunky clear bowl with white banded design id please

[Margi]

Good afternoon all
Been having a cant get anywhere time with this lovely bowl.  Very heavy with the glass being about 3/4 cm thick.  Crystal and clear with three bright white arty stripes inside.  very concaved centre.  The inside bottom being at least approx 2cm from the actual base.  Lots of wear on the base although this doesnt show on this pic.  In excellent condition.
I think it looked quite contemporary until I saw the wear so that got be thinking 70s perhaps unless it has had a particularly bad life so far. I am thinking italian.
Help
