Celadon vase - origins unknown

This celadon vase is 6" high x 6" in diameter and is not marked. It weights 2 lbs 11 ounces ( 1.22 kg). It has an incised pattern under the glaze. Guessing it is newish and Chinese or Korean, since it looks new. It was just $.99 so I did not have the heart to leave it. I think it is pretty good work, no matter where/when it was made.

I got decent images using natural lighting and that somewhat skewed the color in the second image, removing some of the green element in the color. The other three images are closest to the actual color. I included the second image as a it gives a different perspective of the design features.
