Each of these diamonds are real diamonds. The only thing that makes them different from a natural diamond is that they are “grown” inside a laboratory using cutting edge technology that replicates the natural diamond process. Since lab-grown diamonds are made of the samematerial as natural diamonds, 100% carbon, they are chemically, physically and optically the same as those grown beneath the Earth’s surface. Lab-grown diamonds are real diamonds and will last forever as will the natural diamonds. The only difference is there origin. They are not cubic zirconia.
The GIA offers laboratory-grown diamond grading reports using the same color and clarity boundaries as the grading system for natural diamonds. Lab-grown diamonds often have 
minimal inclusions and blemishes like you would find in top grade natural diamonds. They are not visible and will not cause a cloudy appearance or lower the durability of the stone. Lab-grown diamonds can be as much as 20-40% less expensive as natural diamonds.
