Originating in Bali, harmony balls contain tiny brass xylophones that create soothing, magical sounds when shaken. Used for relaxation and meditation, given as a keepsake of timeless friendship and love, or worn by expectant mothers so newborn babies will recognize the sound of their mother’s harmony ball when they are born, harmony balls are a lasting vestige of an ancient civilization. This handmade pendant consists of abalone (mother of pearl) shells fitted perfectly within a sterling silver cage. The diameter is 1 inch. It comes with a 30 inch silver chain necklace.
