Stunning vintage Art Deco genuine carnelian (the gem stone, not carnelian colored glass) and crystal knotted bead necklace. Measures 20" long, beads are graduated in size from 7/16" x 3/16". Separated by faceted crystal beads. Sterling silver spring ring clasp is hallmarked "Sterling" and well tarnished. In excellent condition, these have never been re-strung- all original and have been very well babied. You may wish to eventually restring these onto modern cord, but they seem quite secure and very wearable. Stunning! Circa 1920.
