LIGHTWEIGHT. This is a curb chain. It’s adjustable up to 8 in and down to 7.25. All of my jewelry is handmade. Chains and charms are made from basic metal materials that are COLORED gold, silver, copper, etc. (listing will contain info if/when genuine metals are used). Some charms contain enamel. Most measurements are approximate. See ruler in photo. Message me with any questions. I hope you’ll enjoy my jewelry.
