Some consider Picture Jasper an anti-negativity mineral and others see it as an energy balancer. We just consider it a beautiful stone reflective of earth's natural colors. We've used these jasper beads in a double wrap bracelet 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. Currently we offer the wrap in a small (37.5-39 cm), medium (39.5-41 cm) and large (42-43.5 cm) . For your size, loosely measure your wrist and double.
