It looks old to me. And not Chinese either. I'm thinking it could be early 1900s, Bohemian/Czech.
Loetz wasn't the only maker of iridised glass like this, everyone was doing it back then as it was in fashion & the manufacturers copied each other all the time.
Loads of "minor" manufacturers made this type of glass, but it all gets called Loetz.
English firms in Stourbridge made this type of iridised moulded glass too, & I'm even thinking that I've seen that tulip design on a piece attributed to an English maker.
Either way, it is old & no way it's Chinese.
