This white nephrite jade carving of a pig dates from the Han Dynasty (206 BC-220 AD).
It measures 4 inches nose to tail, by about 1 3/8 inches tall by 1 inch in width.
It is an overall white color with traces of brown oxidation in the crevices.
It has areas of irregularity on it's flat and rounded surfaces that create an almost spider web like pattern (off white on white colors).
It is in excellent condition except for one drill hole in the tail which does not appear to be contemporary with the piece. It was most likely added so it could be worn as a pendant.
