I agree with Lustrousstone - unlikely to be Murano. I also doubt a Chinese origin with what I can see so far.
The main problem I have about making a suggestion is that there is no complete photo of the base.
If the base has a pontil scar I would assume a small studio is most likely.
And if has a pontil scar, it would be helpful to know the place it was bought - location not the shop.
