Part of the translation - from Dutch I think - reads " ......... light old-pink/purple iridescent vase attributed to Loetz, not marked."
Do we think this is an accurate comparison of the surface colour of the op's glass ?? From what I can see - and appreciate screen images can be less than reliable - I think the surface pattern differs between the two pieces, but I stand to be corrected.
The linked item may or may not be Loetz, but if you're going to provide am unsupported attribution then why not go for a big name - makes for good sales pitch.
