This is an incredible Chinese carved bead necklace. The beads are rare green chrysoprase and black obsidian. The large obsidian beads have and shou signs on two sides and a dragon on one side and a phoenix on the opposite side. The obsidian beads are beautifully carved and they measure 22mm. The green chrysoprase beads are carved in the traditional dragon/shou pattern. They measure 14mm. The necklace has four sets of devil's work rings. The 3 interlocking rings measure 38mm long and 17mm wide. The chrysoprase rounds are 10mm. The necklace is 31.5" long and it is endless style. The necklace is spectacular on. Between the color, carved beads and the interlocking rings it is a jaw dropping necklace.
