And if you go to Baccarat, you will find a couple of shops right across the street from the real Baccarat showroom with Chinese paperweights that have a 'Baccarat' label on them (it has the shop name and address in small letters, and Baccarat in large ones)! I know Baccarat took one of them to court some time ago, but they are still at it.
Similarly, a 'Murano' label is not the same as a 'Made in Murano' label. And all the rogue traders have to do, for example, is give the base of a Chinese weight a quick polish and then they can put on a 'Made in Murano' label without being prosecuted.
