A one-half inch 14K yellow gold Imperfect Heart set with a 3mm natural diamond. The heart hangs from either a 16 or 18-inch, 14K gold 1.3mm rounded box chain; total gold weight for the necklace on a 16-in. chain is 7.4 grams. The last photo above shows the heart next to the 18K gold heart that is also available~ 14K on left, 18K on right. In stock and ready to ship 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
