Each imperfectly shaped heart is handmade and one-of-a-kind, so please allow 2 weeks from the order date for your product to ship. The large hearts are approximately one-half inch and are thicker than the smaller hearts. This is a good choice if you want to wear it on a more substantial chain, as shown above.  The heart is made from Argentium silver, which is a modern, tarnish resistant silver alloy similar in appearance to sterling.  A gemstone can be added to the large silver heart, email or call me prior to purchasing. 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
