The basic idea behind the design is to use geometric, voluminous shapes which are covered with a patterned skin. This creates an interplay of clarity and distortion of transparency and exclusion. This fascinating and simple idea creates limitless variety of shapes and fits in perfect harmony with the possibilities of rapid-prototyping, because everyone can customize his personal unique jewelry which is than individually manufactured. The design options with parametric design and serial production with rapid prototyping merge into an absolutely unique piece of jewelry - a monomer.
