A wonderful example of cherry amber bakelite, with marbling/swirling apparent when a light is shone through the beads.
The necklace measures 32 inches long, weighs 70g and has a screw fastening as seen in photos. It fastens flushly and firmly.
The beads graduate in size, and appear to be strung on a cotton/linen cord, there is some light fraying in various places, see photos for examples of this.
