Abstract
The present invention is directed to a jewelry element which includes two layers—a cladding layer and a substrate layer, each layer being its own alloy. The cladding layer and the substrate layer each include a base metal such as silver or gold at the same percentages so that the resulting jewelry element can be labeled in accordance with one or more industry-wide requirements. The cladding layer is further enhanced by introduction of a metal providing additional hardness when included in the alloy. By limiting the 'hardness' metal or metals to being deposed only in the cladding layer, less of the hardness metal need be used, thereby reducing cost yet retaining the requisite hardness characteristic. Each of the alloys may further contain other metals for any of a number of reasons, including but not limited to, tarnish resistance.
