Topic: Murano type paperweight with spirals

[Anne E.B.]

Is this a Murano or Chinese paperweight please?  I've already got a Murano ribbon latticino one of a similar colour shown with it in the last image, but this one is very different.

I'm not too sure I like its wormy spiral tubes if I'm honest (not too sure what you call these things).  The interior is visible from the base, and is just the same splodgy blue seen on the outside.  I don't believe its new as there is quite a bit of wear on the base.  Any ideas would be most welcome

Definitely Murano.
