A lovely vintage necklace and from the quality of the cinnabar I believe this could be a mid century necklace. Chinese Export measuring 30 inches around in black onyx beads,steel beads,and lovely vermillion cinnabar, Screw closure (another indication of age). The pendant is a Tang dynesty style horse in silver metal.No mark for sterling. Wonderful condition a piece I purchased at the huge antique expo in Portland. I do consider offer and always combine shipping on multiple orders.
