The Diamond Crown, from Edison Studios, was a 1913 American silent film (short) written and directed by J. Searle Dawley. It was the first of three “Kate Kirby's Cases" detective stories made in 1913 for Edison before Dawley and actress Laura Sawyer left Edison for Famous Players Film Co. later that year, where they produced three more. This film was also Justina Huff's debut in motion pictures. The Diamond Crown was released in the United States on July 12, 1913. This film is considered “lost.”
