Vintage carved stone yellow serpentine jade wood Amber-like beaded necklace

This is an Asian vintage necklace with perhaps a serpentine or yellow Jade stone carved pendant. The pendant has weight, but the necklace beads are very light so makes it quite wearable. Not sure if the beads are genuine Amber or lucite. They are interspersed with Wood and orange crystal beads. Necklace is 22 inches in length and a couple more inches to adjust on the chain. The pendant itself drops approximately 2 inches.
