This Haines Butterfly Necklace is 16 inches. I am so thrilled to share this collection with all of you! I can truly tell you that every piece can be worn for years to come. The heart behind this collection is what really makes it special. My little boy is one of the special few who has battled epilepsy. While he has been seizure free almost two years since his brain surgery there are so many children who still suffer daily. I am so humbled that Lisi will be giving a percentage of this collection back to the Epilepsy Foundation as they continue to fund research to cure Epilepsy. The Butterflies in this collection represent all of these children and adults who are all different but so beautiful in their own special way. I hope that you love wearing these pieces as much as I do! And I hope when you wear them you think of these beautiful people who fight this fight, just like Haines. XO, Avoly
