This is a hand made mood color change necklace. It comes with an 18 inch bronze chain. If you need the chain longer or shorter please send a message with your specifications! This necklace handmade by me. It's impossible to capture the wide range of colors it has but it goes anywhere for a black/brownish to a bright blue/purple and EVERYTHING in between! Every item is hand made by me! The acrylic stone is set in a 18x25mm setting. All mood jewelry comes with a small chart explaining what the colors mean! Please note that mood stones in general aren't meant to be submerged in water. I offer free shipping to the United States, for international I do offer combined shipping. Any questions please send a message! Thanks for looking :)
