Sae Honda is an Amsterdam-based jeweller who collects plastic rubbish on the street and melts it down into a unique, artificial rock. She observes the qualities of each rock and then cuts and polishes them to create plastic gemstones. The inspiration for the project was sparked by a new kind of rock discovered in Hawaii, which contains plastic fragments. It is said that the rock cannot erode, but will remain in the ground until perhaps future generations discover it, like some kind of precious stone. Honda’s imagination took this a step further, leading her to create rocks that contain memories of today. This book presents her collection of self-made rocks and the stories behind each.
