Larger than usual, the ritual disk nippled softly on both
sides with finely incised comma
scrolls in the Warring States manner, inner and outer
rims, reverse identical, the central hole and rims slightly
irregular in excellent imitation of ancient workmanship. True
nephrite jade of the very palest celadon (usually called "white")
with some light tan areas, extremely translucent.
Top quality reproduction. Another view here.
