This Jade Bird is from the Shang Dynasty of 3000 years ago.Note the following:
01.The decoration is accomplished with thin double incised lines.
02.The decoration is on both sides.
03.The Jade is of highly translucent white Nephrite.
04. There is no hole for attachment,or is not drilled yet,suggesting astill a WIP(Work In Progress) especially as considered the polishing is not shiny enough.
Still a valuable Antique Jade Bird of the Shang Dynasty.
