Hello and welcome!
I am no Iittala ex-spurt, and I don't know what lighting and photography conditions you have there, but the colour of the glass looks (to me) to be far too yellow for Iittala.
It's normally a really clear sort of clear - no blues greens or yellows in it.
I also get my textures mixed up, but does this not look like an Ingridglas texture?- one often confused for being wfs.
I can't see it (the texture) terribly well from the pics, but the clear glass colour from Ingridglas isn't quite as absolutely, utterly clear as Iittala is.
