The chain is about 2mm thick--I would describe it as a rounded box style. It has a snap clasp. The gold finish on both the pendant and the chain are not the typical 'bright yellowish gold' that is often seen--they are more of a subdued gold--but they match. The total length of this necklace is about 16 inches. I hope that you like it!

Note: Due to the fact that most of my items are made from vintage components, they may show very slight wear or have slight imperfections. But you can buy with confidence, as I am careful to only use parts that have barely noticeable imperfections.
