Good green and translucent "Bi" Symbol of Heaven" pendant on silk cord adjustable necklace.  Bi pendant is 30 mm diameter across, and 5 mm thick.  The cord is knotted in a way that it adjustable by sliding the "knots".  Well polished, much more pretty than the photo shows.  

Purchased during our jade shopping trip in China in Guangzhou Jade Market.

One only.
