Cased Glass Swan (Murano?)

My lovely sister gave me this lovely Glass swan for Christmas. she bought it in a charity shop and it was sold as Murano, but most things like this are sold as Murano, but is it? It's 9" tall and is cased clear glass and the centre is dark red glass which looks black where it is thicker, with silver sparkles. I have been trying to find one similar. Have looked all through the Murano Zoo etc. The one that looks nearest to this was from Vetreria G Campanella, but I can't find out much about the company! It's the base I am not sure about? Its a lovely orangey amber colour, but it's very new looking!! Any help would be appreciated.
