The Van Groode Jewelry Company purchases the Jarvis Diamond, worth a quarter of a million dollars, but also named the Devil Diamond because the owners or possessors of the stone become cursed. Hoping to make the diamond more marketable (as well as eliminate or lessen the curse), the jewelry company decides to have the stone cut. The job is handled by Peter Lanning, an expert gemologist who operates low key out of a boarding house in San Juan, where he lives with his daughter Dorothy. Stevens, a member of the company, conspires with a jewel thief Morgan to have the stones stolen. To make a front for his activities, he has his henchman train a young kid Lee for a prizefight, while Morgan, aka Moreland, researches for a book on Joaquin Murietta. Jerry Carter, an insurance adjuster hired by the jewelry company, also stays at the boarding house also researching a book on Murietta. When Morgan has Lanning abducted and Stevens killed (to get the stones for himself), Jerry, Lee, and Dorothy have to act. The film is strictly run of the mill with no surprises or anything new going for it. Darro's character seems to be picking fights with Morgan's henchmen every 5 minutes (and weak fights at that). Richmond spends the entire film walking around and looking through windows (as does Fiske as the Morgan). I did enjoy Baker's character (Yvonne) as the teenage girl with a crush on Lee and unable to take his hints to scram. The production values are nothing to write home about either. Rating, based on B-movies, 4.
