I couldn't believe what the article had said. It claims that scientists at the Carnegie Institution of Washington have found a way to makediamonds even harder. Crazy! As most of us know diamonds are one of the hardest materials on earth. I couldn't believe that human machinery could make something hot enough to match the heat of 150 kilometers below land and into the earths core. First they tried to make diamonds harder by doing a process called chemical-vapor deposition. The purpose was to add more carbon atoms to previously created artificial diamonds. With every test they had to cook all of the diamonds under intense heat and pressure. Believe this: The new diamonds were so hard that they broke $10,000 in equipment while testing them. Scientist couldn't dent or scratch them with their machinery. To be continued......
