Therefore, this process has no room for failure. The conventional process requires designers to present their design to the manufacture before the product is manufactured, thus the representation will be error-free in terms of translation of the designer’s intended concept of the actual concept. This is ideal as both designer and manufacturer come together to agree on a final product hence avoiding inaccurate or incomplete messages in the representation between both parties. Unfortunately in reality, errors are bound to occur. This is especially so in the translation from design to production stage. There is no perfect translation, resulting in certain intrinsic values lost. Translation error occurs in two areas. First error occurs within the production stage, where the sketch is translated into a design image. Followed by a second degree of translation or transformation error in which the design image converted into a production drawing. Therefore causing a second round of intrinsic values lost. In order to solve this problem, designers have to acknowledge such a problem and have to find a way around it. The reason why this is important is because jewels possesses implicit beauty, the failure to consider this part of the equation may cause the designer to miss some fundamental aspects of the design problem (1990, Petroski). Referring to the figure 2 (below), the quality of the hand-painted jewellery design depends
