Interesting piece closer to the "Galaxy" style than the Murano pieces that use the same technique. I'll attach a "Galaxy" vase I have that looks quite similar yours, especially around the base. However, on looking at the colour and general shape of the piece I wouldn't say Skrdlovice, and I feel very safe in saying that now that Robert has also said it.
It is a well used Murano technique. Fratelli Toso used it to make their overshot pieces and it was also used much earlier. I've also seen it used in other places, including American Studio glass. That said, I haven't a clue who made your piece, but I'd keep looking as it looks like a nice piece of glass. It took me over two years to identify my "Galaxy" bowl, btw.
