The narrative style of Blood Diamond is simple and direct, but it is plain and moving, and the brilliance of human nature is even more brilliant in the illegal diamond trade full of blood and desire. In that hellish land, some people are nostalgic, some people are eager to escape, and diamonds have become a bargaining chip that they cannot give up.

As for its connotation, I think this sentence in the film can be made very clear: If those young people in the United States knew that diamonds would pay the price of their lives, they would not spend three months' salary to buy a diamond ring, which is indirectly funding the war. The pun on the title also reveals this truth. Blood diamond is not only a precious diamond, but also a symbol of the evil blood of countless people.

In the opening scene, fisherman Solomon lit a match in the dark, and in the last scene, he stood on the podium in a suit and tie, lighting up the dark illegal diamond trade.

Solomon is a very lucky patient. People suffer because of war, because of the evil illegal diamond trade, because of bloodshed, because of boy scouts, because they can't live in peace, because everything around them is too dark. The image of "light" has formed a concern throughout, which makes the theme of Blood Diamond more profound and meaningful.

On the land of Africa, turmoil, violence, drugs, guns and blood have become the norm of people's lives. Archer, the man, is the representative who wants to escape from this hell. He is so eager to get the diamond that he wants to leave completely. After so much, the good side was awakened, and he sacrificed himself to let Solomon and his son escape. Archer's transformation from selfishness to selflessness is the embodiment of the humanitarianism in this film.
