It's an interesting piece. However, I'm leaning away from Murano. Battuto is increasingly done all over the world (see Dirk's recent post for an example from China). The quality of the glass, the finish on the base, and the weight all say not Murano to me. I'm less sure where it was made, though. Perhaps China, India or Romania, although that hardly narrows it down. That's not to say it's not an intersting and very decorative piece.
As ever, I'm keen to hear what others say.
