About Lab-Grown Diamonds

Lab grown diamonds have the same sparkle and visual characteristics as natural diamonds, but because each batch is produced to the same standards, lab-grown diamonds are more affordable than natural diamonds. New production capabilities also mean that lab-grown diamonds can be created in brilliant colours that are extremely rare in nature. Both laboratory-grown diamonds and natural diamonds consist of pure carbon in the same cubic crystalline form, meaning that an expert can distinguish between the two with the aid of a high-tech machine—but not with the naked eye.
