Darmond was reportedly a lesbian, but she has also been referred to as bisexual. Although performing in a substantial number of films over roughly 13 years, she was known in Hollywood's inner circle as the lover of actress Jean Acker, the first wife of actor Rudolph Valentino. Darmond also socialized, as did many struggling movie actresses of that era, with actress Alla Nazimova, who was allegedly a former lesbian lover of Jean Acker, although it has never been verified that Nazimova and Darmond were linked romantically. Darmond and Acker attended parties at Nazimova's Garden of Allah, an imposing house on Sunset Boulevard named after a Robert Smythe Hichens play in which Nazimova had appeared.
