Anita:
My suggestion is Murano, and most likely a good maker. I'm attaching a picture of a little Venini bowl I have that has a similar combination of small and larger bubbles. The inside of the bowl feels lumpy, while the outside is smooth.
I was going to ask if you'd looked closely for a Venini mark on the bottom, as they're often very faint, but I'm sure you've done that.
It took me a while to get round the slightly unexpected colours in your piece.
