“The project is seeking couples who want to donate their bone cells - a couple having their wisdom teeth removed would be ideal. . . The couple's cells will be grown at Guy's Hospital and finished bone tissue will be taken to a studio at the Royal College of Art to be used in the design of a pair of rings. Following consultation with the couple, the bone will be combined with traditional precious metals so that each has a ring made with the tissue of their partner.”
