According to Film Daily, the ring was given to Valentino’s lover, actress Pola Negri (pictured above in center). Shortly after, her Hollywood career swiftly came to an end, and she became ill (via Here There Be Monsters). Thinking the ring might actually be cursed, Negri gave it to singer Russ Columbo. Days later, he was shot and killed by a friend. Columbo’s possessions, including Valentino’s ring, then went to Joe Casino. Casino was a good friend of Columbo and put the ring on display. Believing the curse was nothing but a fabrication, he eventually decided to wear it. Per Rick Wayne, Casino died when he was hit by a truck shortly after. His brother, Del, inherited it and kept it locked in his home.
Ripley’s states that Del’s home was robbed, and the thief took the ring. Before he could make his escape, the police arrived on the scene and shot him dead. The ring was still in his pocket. Later, a film director requested the ring for Jack Dunn, a figure skater who was being considered to play Valentino in a biopic. Dunn wore the ring and died of a blood disease weeks later. It was then placed in a Los Angeles bank vault owned by Del. However, the bank also encountered a bout of misfortune, including robberies and fires. Our Community Now reports that the ring’s current location is unknown. A portrait of Valentino, Negri, and the ring sold at auction in 2017 for nearly $200,000 (via Bonhams).
