Henri Moissan (1852-1907) received the Nobel Prize in Chemistry in 1906. In 1892 theorized that by crystallizing carbon with pressure and heat from molten iron he could make diamonds. The then set out to prove his theory by designing and building an electric-arc furnace. He subsequently was able to product several tiny stones that had the same properties as mined diamonds. Thus the start of the man made diamond

Man-made diamonds are not considered synthetic diamonds because they do have the same properties as real or mined diamonds.
