Each imperfectly shaped heart is handmade and one-of-a-kind. The small hearts are approximately one-half inch and each is hand fabricated from Argentium silver, a modern silver alloy similar in appearance to sterling but tarnish resistant. The pendant hangs from a 1.5mm cable chain, and the pendant can be worn from 16-18 inches. This is a nice feature for accomodating various necklines and layering with other necklaces. The heart pendant can be stamped on back with initials or a date, indicate at checkout. Please allow two weeks for delivery, shipping within the U.S. only. *For me the heart collection symbolizes synchronicity, love, and imperfection and represents both the good things and people who cross your path when you need it the most and the imperfection of life. Each is somewhat irregularly shaped and are modeled after the heart-shaped rocks I’ve found on trails over the years. Other people have told me that life guarantees our hearts will get beaten up along the way, and that's what the hearts represent to them. Thank you to everyone who has purchased hearts. xo Cheryl
