Abstract
A jewelry rope chain having links interwoven together to form a double helix configuration. Each link has a cross section with the largest transverse distance across the cross section defining a first dimension. Each link has a interior space and a gap along the periphery of the length. The widest dimension of the interior space in a direction consistent with the direction of the gap has a dimension which is less than three times the first dimension. Thus, ratios of approximately 2:1 can be achieved.
