Jade statement necklace - estate

Large estate necklace made of solid carved jade pendant and beads. Pendant measures 1"X2" inches, and the necklace measures 28" inches long when unhooked. One corner of the pendant was once broken and reattached with glue, but you can only tell by looking closely at the backside, you can't see it at all from the front (see the last picture). This was an estate piece brought back by my great aunt who lived in Africa and China for many years in the mid 1900's.
