Different finishes, polished and matte patina or gilding, give contrast to highlight the three-dimensionality of the jewellery. The diamonds in the 4C collection are created with 3D-technology to resemble the outlines of different gem cutting styles made with precise mathematics and technique, and it opens up the beauty which is usually left unseen. Collection has four different cuts: brilliant, princess, marquise and pear cut.
