This is a Chinese green jade Peking art glass plate or shallow bowl. The bottom is etched with the word “China.” The date is circa 1890.
The plate is 12 ½” wide and about 1 ½” deep, so about the size of a charger.
The middle of the plate is deeply lobed and extends out to sharp points on the edges. There is the depth of the 1 ½” because of the lobes.
There are some tiny air bubbles in the glass. There are no chips, nicks or cracks.
