"Celadon is a term for ceramics denoting both a type of glaze and a ware of celadon (color). Celadon originated in China, and notable kilns such as the Longquan kiln in Zhejiang province are renowned for their celadon works. Celadon production later spread to other regions in Asia, such as Japan, Korea and Thailand."
Some celadon has been found that dates back to 25-320AD.
From my research, I was able to determine that your celadon 20thC statue has a retail art gallery value of $275-300 assuming perfect condition.
