Multi strand stone bead necklace with a large nephrite jade pendant

Four strands of stone beads in shades od tans and browns. I am not sure what kind of stones they are. There is a large pendant with dragons on the edges that tests as nephrite jade. It is an olive green color. There is a beautiful silver tone clasp with a hook. Measures about 19 1/2” and the pendant is 2 1/4” long. In very good condition. It looks like it is artisan made.
