What Is The Difference Between Rope And Diamond Cut Cable Chain?

The main difference between these two chain types is the look and thickness. 

The rope chain consists of many small links crafted to give the effect of strands spiraled together. It is a dainty thin style chain.

The diamond-cut cable chain consists of links that interlock with each other, with diamond cuts on the side. The rope chain is approximately 0.6mm thick, while the curb chain is slightly thicker at approximately 1mm.
