I don't know what the hell it is either!
It appears to be well-made. The straps gently meld towards the top, the pulegoso seems good quality.
I *think* it has a completely flat polished base, but when I enlarge the pic all I get is a mass of pixels so I can' really tell.
But then the rim is a bit thick and unsophisticated, and the colours do seem rather bright. It is also quite substantial.
My guts are suspecting contemporary Chinese. The quality has improved vasty recently and they are also using some very sophisticated techniques now.
I think it will be lovely as a usable, practical flower vase .
