Pink Gods (1922)

John Quelch, the owner of vast diamond mines, is constantly fearful of theft and convinced that any woman will "sell her soul" for diamonds. He deals harshly with any employee caught stealing and has Lady Margot Cork watched while she is visiting Lorraine Temple. John and Margot fall in love, but she cancels their engagement when she learns of the "brutal" punishment of Jim Wingate for swallowing a diamond. John sees Lorraine's weakness and tempts her with a fortune in gems. She makes advances, but John repulses her with the explanation that he had intended only to show her the error of her ways. Wingate dynamites the mine and the mansion; Margot and Lorraine's husband arrive in time to hear Lorraine thank John for the lesson before she dies; Margot and John are reconciled. Conflicting synopses create doubt that Lorraine actually dies in the explosion.
