The work of Esther Brinkmann is characterised by the meaning she bestows on the ring, its relationship to the hand and, perhaps most surprisingly, to its case. The Swiss artist prefers processed and textured materials, which now also include new component forms, techniques, and substances since her time living in China and India. She established a further education training program in jewellery design - a unique undertaking in Switzerland - at the Haute Ecole d'Art et de Design (HEAD) in Geneva. Here, her knowledge and autonomy in her work have already shaped several other artistic careers. This publication presents Esther Brinkman's oeuvre from the past 30 years and highlights for the first time the remarkable strength and the freedom that distinguish the artist's rich career.
