Necklace is LIGHTWEIGHT, chunky textured double-link chain measures at 16 in, but with fixtures extends to 17 3/4 in, and it can be shortened using provided links. 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. If you know your size, I can customize the item for you! Please ask about (and confirm with) me about combined shipping BEFORE any multiple purchase is made, as I cannot refund multiple shipping payments once they’re made😃 I hope you’ll enjoy my jewelry.
