Between 1939 and 1945, Nazi forces inside occupied countries confiscated an untold amount of treasure, including a flawless, 47.05 caret blue diamond known as the Blue Regina. Later, it was mistakenly sent to the United States, and arrived just prior to the start of World War II. Throughout the duration of the war and after, its whereabouts remained unknown.In 1951, a well-funded U.S. bound expedition is formed by a noted Berlin gemologist. Unfortunately, news of his expedition motivates others to search for the diamond, while applying their own set of rules. That doesn't bode well for any of the participants, especially when the prize is valued at more than three million dollars.The Blue Regina evokes romance, obsession, deceit, desperation and hollow hope, in a deadly competition to possess a world class diamond.
