Darmond was pretty, slender and starred in many notable films of the period, but she never was able to break through as a leading actress in big budget films. Most of her roles were in support of bigger names of the time, and most of her starring roles were in smaller, lesser known films. She appeared in "Below the Surface" (1920), starring with Hobart Bosworth and Lloyd Hughes, and that same year played in "A Dangerous Adventure", produced and directed by Warner Brothers. This led to her being cast alongside Boris Karloff in the mystery thriller "The Hope Diamond Mystery" (1921). In the July edition of "Motion Picture Magazine", she was featured in an article by Joan Tully entitled "Mantled With Shyness (A Word Portrait of Grace Darmond)".
