Momentum (Latin for impulse, moment) explores the potential of participatory aspects in the design of one-off items and serial jewellery work. The customers are specifically integrated into the physical evolution process of their one-of-a-kind pieces. Thanks to the playful interaction, unique moments are literally suspended, and the resulting rings fit the hands of their wearers like a glove. Partaking in this remarkable process intensifies the personal and thereby permanent relationship to the individual items of jewellery. Momentum is uniqueness in serial form.
