It certainly looks like something I would believe to be Czech, or maybe German, Austrian or French (if I had to look elsewhere, mostly because of the use of the colour in combination with the lines) instead of Murano.
If it were Czech, my observation would be that the form may look a bit Chribska, but the colour looks more Zelezny Brod (all neodymium Czech pieces I have are ZBS). Unfortunately I'm only confident when it comes to pieces that very clearly are typical of their factories, and this one isn't in my range of knowledge, sadly.
But I'm a novice Czech collector, so I'm hoping someone else with more experience can point in the right direction.
