The Devil-Stone is a 1917 American silent romance film directed by Cecil B. DeMille and co-written by his mother Beatrice and his sometime lover Jeanie MacPherson and starring Geraldine Farrar. The film had sequences filmed in the Handschiegl Color Process (billed as the "DeMille-Wyckoff Process"). Only two of six reels are known to survive, in the American Film Institute Collection at the Library of Congress. This was the last of Farrar's films for Paramount Pictures.
