This necklace featured a piece of antique jade huang.
Jade huang is a form used for jade pieces dated all the way back to the Neolithic Age, some 8000 years ago. The arch shaped form started as a part of the costume for the sorcerer when practicing black magic. By Shang dynasty, 1000 B.C., it has developed into a costume ornament which acted as a symbol of social status. The fashion of jade huang ended and took over by the jade pei, a more decorative pendent.
This jade huang has a carving of a dragon pattern.
