Jewelry Design Flaneur Jewellery Collection by Qiuyu Yang Flaneur is a jewellery collection that turns personal movement data into wearable form. Each piece translates a recorded walking route through a city into a three-dimensional shape, so every wearer receives a unique design. The collection is produced by three-dimensional printing and uses precious metal and opals. The changing colours of the opals refer to the day and night life of London, the city used as the starting point. Flaneur lets people keep a lasting record of daily journeys and travels.
