Icelandic designer Hafsteinn Juliusson has created a set of jewelry that will really grow on you. His Growing Jewelry features inset Icelandic moss that owners must regularly water and trim — a practice he hopes will help urbanites connect with nature. The mossy rings and necklaces, which Juliusson describes as “a clash of jewelry and gardening; couture and organism,” are available at the Reykjavik Art Museum where they live under growing lamps.
