The Sins of Rosanne (1920)

"Revealing the double life of a girl who sold her soul for diamonds. Laid in the famous jewel fields. Athrill with villany, secrecy, love and the mystic spell of Oriental sorceries."

Roseanne (Ethel Clayton) has grown up near some diamond mines in South Africa. As a child, she became ill and a Malay nurse, Rachel Bangat (Fontaine La Rue) promised to cure her. That she did, but she also worked some voodoo on the child, who, as a grown up now displays a powerful desire for diamonds and the ability to throw evil curses on those who displease her.
