The ring that was so closely associated with the Magnum PI. series, also has great symbolic and historic meaning.
In early history, the Cross of Lorraine, also 
known as the Patriarchal cross, was carried by the Knights Templar during the Crusades. It later become a symbol of a free France after the liberation of France from Nazi Germany.
This kind of symbolism is often expressed in personal items, such as rings, that bear a sentimental meaning of belonging to or celebration of a cause.
