A heartbeat signals life. Your heart is in constant motion, circulating life-sustaining blood through your body 24 hours a day. That it works is a gift beyond measure. This cardiogram heartbeat necklace is a reminder to use that gift to live fully and to love with passion. Made from a gold, silver, or black plated zinc alloy (nickel, lead & cadmium free), the pendant is 1 1/2 inches wide and the chain is adjustable from 17 to 19 inches.
