ABSTRACT:
By means of having taken advantage of certain physical properties of solids with a manufacturing process of incrementally deforming hollow links, there is produced new hollow simulated diamond cut multifaceted jewelry rope chain, which results in a product weighing up to 60% less than its solid counterpart, but which in its aesthetic looks is similar to solid diamond cut jewelry chains, and furthermore, with a hardness greater than the same hollow chain that has not gone through the process. This invention presents a new diamond cut chain, which costs a fraction of the price of a solid chain aesthetically similar, and in which the chain may vary in cross-section, such as forming a square or a hexagon.
