The Moonstone is a 1915 silent film directed by Frank Hall Crane.

The film stars Eugene O'Brien as Franklin Blake, Elaine Hammerstein as Rachel Verinder, Ruth Findlay as Rosanna Spearman, among others.

When Englishman John Herncastle steals the diamond, the three priests guarding it are stripped of their caste until it is returned.

Franklin and Rachel are reunited, and the priests return the stone to the Buddha's eye.

[1] Lynde Denig of the Moving Picture World praised the plot for its complexity and twists, stating that "a tale of this description must be followed with close attention, and in either case the reward will be an ingeniously contrived, highly colored romance - a story pleasantly removed from the prosaic facts of everyday life".
