Abstract
A jewelry rope chain formed of a number of links of wire of a cross sectional configuration. The links are intertwined to form an outer appearance of a double helix. A predetermined number of the links is required to form a full helix cycle. At least some of the overall geometric shapes of the links within a full helix cycle are different from the overall geometric shapes of the other links within the same helix cycle. The chain can be formed either by initially selecting the links of different geometric shapes and intertwining them in accordance with a desired sequence. Alternately, initially the chain can be formed of uniform links and thereafter the entire chain rolled or reshaped so as to reconfigure the shape of at least some of the links with respect to other of the links within a full helix cycle.
