Pearl is one of the most loved and desired gemstones. This is a combination of lava bead and freshwater pearl. This bracelet is approximately 7 1/2 inches. The lava beads hold essential oil so you can have the aroma on the go. How to diffuse: drop or rub the essential oil of your choice on a lava ball or two. Let dry completely before you wear the bracelet. This will allow the oil to last longer.
