The basic elements of this series of necklaces are the twelve Chinese signs of the zodiac. Each of two elements can be combined individually to spherical pairs which then, conforming to the elements of yin and yang of a Chinese Tai Chi diagram, match and unite like a hug. In this manner, various people can exchange the different components and in that way express their mutual affection. Each of the 24-carat pieces of jewellery is produced in a 3D gold printing process.
