I am mystified as to why this vase holds such an attraction for me as it's not my prefered style at all......

21cm - 8.5"
So what has it got that's so special ?
Quality ?
Well is ok to good IMHO, well crafted with nothing to complain or rave about.
It's nicely finished with no glaring manufacturing faults.
Evenly cased in clear glass.
Rim nicely rounded, nice weight without being "heavy".
No pontil mark - base just pushed up a little and very evenly.
Technique ?
The technique is nothing special as far as I'm aware - hopefully anyone who knows better can set me straight on that.
Value ?
I don't care what it's worth as it's not for sale
Maker ?
I genuinely have no idea myself and I have a feeling it's not going to be easy to ID. It would be nice to have some idea so guesstimates / votes / speculations are most welcome. thank you
