Mi-Ah Rödiger / Delphine Boël
Amsterdam's Mi-Ah Rödiger "makes jewellery that aims at introspection: more than anything, it needs to be experienced by the wearers themselves. [Her] work stems from a deeply felt need to halt the world for a second. She wants to limit the current overload of stimuli by 'switching off', by isolating certain senses." These rings (from her "Soundscapes" collection) don't do her work justice, so check out her site!
