Gorgeous and obviously quality stone bead necklace in a mellow green ranging from a soft medium to a darker green, very much like jade but I believe they are agate. The large, uniformly sized beads are approximately 11mm or about 5/8 inch diameter. Small clear green glass beads in between. Lobster clasp marked .925 for sterling silver. Measures 16 inches in length. Very good condition, beads show no wear at all.
