Make no mistake about it, a lab grown diamond is not fake, it's not synthetic, and its not CZ. Customers ask us all the time, "Is a lab grown diamond real?" The resounding answer is yes they are! The only thing separating a lab-grown diamond and a mined diamond is how they're created. Mined diamonds are created naturally in the earth's crust after pure carbon is crystallized under intense heat and pressure. Our lab-grown diamonds are created in a laboratory after pure carbon is crystallized using high-energy lasers. They are as brilliant and as hard as mined diamonds, because they are a diamond. In fact, an Andrews Jewelers lab-grown diamond cannot be told from a mined diamond by a gemologist, unless they use sophisticated equipment to scan the makeup and arrangement of its atoms. Lab-grown diamonds are optically, physically, and chemically the same as mined diamonds. They are graded using the same GIA grading system used to assess color, clarity, and cut grades.
