Thanks, everyone, for your comments - now I am really confused.

However on looking at all the links, and although I am not too happy at saying it - I think Ross's Rikaro vase seems to be closest to mine.
The reason I am not too happy is that when I had a Rikaro peacock a few years ago I wrote to them and asked where it was actually made - they answered honestly enough - made in the Murano style in China. ( I have since seen that peacock advertised for $495

) (No I didn't keep mine- It was a bit lumpily made which is why I had queried it with Rikaro in the first place. )
However one of the other links has a label which says definitely - Rikaro made in the Czech Republic - so if mine was made there I would be much happier about that

Their web site says <Inherent in these products is the thousand year old tradition of crystal and glass making in the heart of Europe and other glassmakers from around the world> so maybe some of it is made in Europe.
It is a pretty vase, and quite nicely shaped and finished - so it will probably stay up on the shelf next to my real Murano sommerso pieces!.
Thanks again
Jackie
