Lab-Grown Diamonds have the same chemical, physical and optical properties as natural diamonds. They are real diamonds with the same crystal structure and beautiful sparkle, as well as the same hardness. They are also just as durable as natural diamonds. Lab-Grown Diamonds are created in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. These lab-created diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure just like natural diamonds.
