Heng thinks it does not look a Han Chinese face. He thinks it looks kinda Greek !? I think the general shape of the head and ears resembles somewhat the jade face covers used in burials in early Chinese civilization.
The face bead/pendant is made of white nephrite and carved as a rectangular plaque measuring 5cm x 2.8cm and is pierced at one end only. It is carved on both sides in mirror image pattern. There is white iridescence in parts and some slight cracks.
I have seen a similar-looking piece in a jade collector's book and he had attributed it to Xizhou period (1027-771 BC) and described its use as an accessory. I am hoping mine is of the same vintage.

Update 2: for a similar face bead see Freer and Sackler Museum website.
