This pendant consists of distorted triangles, with a symmetric feel but on closer inspection very much an imperfect symmetry.
This diamond is almost impossible to make using traditional goldsmithing techniques, but is very suitable to make 3D printing techniques. From my 3D model this design was 3D printed in stainless steel and goldplated. This pendant has a subtle matte finish.
It is approx 2,5cm high and comes with a fine goldplated ball chain necklace, approx 50cm long. See also the larger version of this design.
