Asian Antique Celadon Glazed Ewer

So I need help to anyone that knows this items worth or value, Origins and other specific’s. As far as my research goes I’ve found it to be some Antique Asian whether it’s Korean or Chinese ‘jade green’ celadon glazed porcelain Ewer, waisted gourd form wine/tea pot. With what looks like incised or inlaid cracked floral design and a long ribbed neck. Possibly from the Goryeo Period 11th-14th Century. Can anyone tell me different or give me more info regarding this item? Please and thank you!
