Beginning with the renaissance of gemstones in jewellery design since the 1970s, Ute Eitzenhoefer, Theo Smeets, Lothar Brugel (ret. 2014) and Eva-Maria Kollischan (since 2014) successfully established the Hochschule Trier in Idar-Oberstein as a creative European jewellery centre. To mark the exhibition in the Stadtmusem Simeonstift in Trier on thirty years of the Gemstone and Jewellery Department, the publication shows an exciting selection of works from the last ten years. Works in creative design and photography accompany diverse approaches that exemplify the contemporary use of a reputedly 'outmoded' raw material. In exploring the aesthetic characteristics of the material and the experimental confrontation with its physical qualities, the gemstone's potential for design comes entirely into its own. Within current discourse it comments ironically, on the one hand, on the unilateral societal ascription as a luxury item; on the other, it functions as a charming and noble object of nature.
