Some consider Serpentine Jasper an anti negativity and bad luck mineral and others see it as an energy balancer. We just consider it a beautiful stone reflective of earth's natural colors, especially green. We've used these jasper beads in a 78 cm (30") necklace accented with a 3/8" (.95 cm) palm wood bead. The jasper beads measure around 1/8" (.3 cm) and are separated by narrow silver discs and beads. The necklace hangs from a handwoven natural colored strap with hand-cast 'S' closure.
