I think this one is a genuine Murano label. The piece is also likely to be Murano, as the milky (is it opalescent?) colour and the threading, including the colour of the threading, is found on a few Murano pieces. I would expect the piece to be older, and yet the label looks relatively fresh. The unpolished pontil is a bit of a puzzle. If not Murano, then Chinese is an option.
