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 wax and cast in brass and goldplated. This pendant is polished and has a glossy finish.
It is approx 4cm high and comes with a fine goldplated ball chain necklace, approx 32″/ 80cm long. See also the smaller version of this design.
