Fabulous piece purchased at Gumps in the late 70s or early 80s. Black Jade with large carved beads and 14k yellow gold smooth rondel beads with double sided clasp. Beautifully polished hand knotted black jade. The necklace is choker style and measures 16" Clasp marked 14k 585; there is a makers mark which is a CH inside a diamond shape. Very sophisticated this piece feels as good as it looks!
