This antique hardstone carving of a reclining ox dates from the Song Dynasty (960-1279 AD) or the early portion of the Ming Dynasty (1368-1644 AD).
It measures about 2 3/4 x 1 1/2 X 1 1/4 inches or 58mm x 31mm x 30 mm.
It is carved from white variegated stone with a small area of pale gray in the center.
It is in excellent condition with a substantial amount of reddish brown oxidation on it's base.
We are describing this as hard stone because it does not pass the scratch test for jade. The possibility exists, however, that it is actually altered jade which has been softened over time and proximity to the elements.
