This is the 26th heart in the collection and the first made out of 18K; each is handmade and one-of-a-kind. The heart is approximately 3/8 inch (10mm) at its widest and is 2mm thick and is on a 16-inch, 18K yellow gold chain secured with a small lobster clasp. 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. xoxo Cheryl
