Any clue about this porcelain green jar

Excuse me......green jar....$350 US...?

Someone had to write green jar...on a label...to put on a green jar...???

That's not even a jar......but a vase !

 

Actually i saw it at an antique shop near by. He was telling it was kind of rare and stuff. Thats why i thought of getting several pics and though you guys might help. Anyway im curious whats so special about that

 

so far , what's special is US $ 350 ..!!!!
Celadon is the only thing that comes to mind.( but this one's sloopy;;...but I'll defer to the pottery folks here....so's I don't get chewed out !!!

 

Those who are colour blind may want to know.

It could have been used as a jar, put a traditional wooden stopper in with some textile, tie a rope under the rim to tighten the textile, and you've got a good storage jar.
It is a very nice jar/vase, great colour, but if it is special, why didn't he put more information on it instead of "green jar"? My guess is Southeast Asian celadon.
