I want all of the Superman fans to consider that the Man of Steel’s logo is in the form of a diamond. I have no doubt that he would be a supporter of man-made diamonds. In Superman III (1983), he even created a diamond from a lump of coal using the pressure and heat from his hands. Superman would love the fact that red and blue diamonds are readily available thanks to man-made diamonds. He would want Lois Lane to have the most remarkable diamonds in existence. Superman would never approve of diamond mining operations. After all, he knew what having your planet destroyed feels like.
