In his artistic jewellery work, Jiro Kamata (b. 1978) deals with optical phenomena in connection with the perception of values. In doing so he also thematises traditional production methods. He processes found and sometimes used materials into rings, brooches and pendants. Kamata's works are generated in respect of an 'experienced memory'; only through experience and interaction with them do they attain their value. Kamata keeps the entire process in view at the same time: from manufacture to performance as worn on the wearers' bodies. Lenses, mirrors, even adhesive tapes offer insights, outlooks and perspectives, link wearers with their environments and query the assumed positions at the same time: How do we see the world and how does the world see us?
