A one-half inch 18K yellow gold imperfect heart set with a 3mm natural diamond; total gold weight is 5.2 grams. The heart hangs from a 16-inch, 18K gold  diamond cut cable chain.  The last photo above shows the heart alongside the 14K yellow gold heart that is also available~ 18K on right, 14K on left. If you'd like a different chain style or length, email me. 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
