Anchor chain is an unusual jewelry chain, that can be fairly heavy and is a nice choice for men, as well as using as a component in jewelry. In anchor chain, each chain link looks like a jump ring with a bar through it. Both cable chain and anchor chain have been used to connect anchors to their ships. You may also find this called mariner chain. You may find these chain links rounded, like a cable chain, or flattened so all the links lie the same way, like a cable chain.
