Diamond is the hardest material in the world. The hardness of diamond varies in different crystal directions, making it possible to grind diamond with diamond. Natural diamonds are formed from pure carbon beneath the earth’s surface. The formation process takes millions of years and requires pressure and heat to transform carbon into diamond. The resulting diamond crystals are transparent, colorless, or colored due to impurities, such as green, yellow, brown, and more rarely, orange, blue, pink, red, or gray to black. They are usually cut in in a brilliant cut to maximize their exceptional light refraction. However, various other diamond cuts are also common. At ORFÈVRE, we see uniqueness in every diamond and prefer to work with those that possess a certain special quality.
