A rope chain formed by intertwining links of a U-shaped cross-section is disclosed, which links are formed from a wire having an interconnecting upper portion, a pair of substantially straight legs extending downwardly from the interconnecting portion, and a substantially open bottom portion or seam opposite said interconnecting portion. The substantially straight legs, results in a rope chain having a full-bodied appearance and a snugger interfit between intertwined chain links. The U-shaped configuration can produce a rope chain that uses less precious metal than if the cross-section of the wire were annular and the links themselves were of annular, toroidal configuration.
