I checked the page. Nothing like your bird there, but I'm sure the Martens' birds are the ones the Chinese modeled theirs on. Yours is Chinese from a couple of years back. The Chinese glass makers change their lines every few years, so they are not made now. There are still plenty of them out there. They are often sold as Murano on eBay. The Chinese often class them as "Murano" in their catalogs, i.e. they are made in the style of Murano glass.
The Martens birds are very different. The bianco nero canes are true black and white, instead of purplish. The canes are applied to the outside of the glass, and not the inside as you see for the Chinese bird.
I am confident your bird is Chinese. No guessing was involved. Still pretty.
