Amazing Japanese Vert de Gris Vase on signed stand.

Bought this amazing quality Japanese vert de Gris Vase only a few weeks ago. It's mind blowing quality..there is a seal mark and numerous painted gold characters too. The body is squat baluster, with a singular horizontal band of lined decoration. There are hues of greens, Reds, oranges etc..On a heavy wooden stand with four character signature to the front. Not sure who made it and when.
