It does seem as if the producers of these items are now using Italian sounding names in order to make buyers believe they may be from Murano. Isn't 'Verrucci' another of these I recall seeing mentioned?
Also, I have noticed that there have recently been appearing on ebay and in charity shops large numbers of the 'Bohemian' faceted flower weights, often with frit names in the top. Could it be that someone somewhere is churning out copies of these? There are rather too many, looking very new and 'in perfect condition' for them to be genuinely old Bohemian weights! Well, IMHO anyway. What do other collectors think?
