  • A lab diamond (also known as a lab-grown or lab-created diamond) is a real diamond grown in a laboratory using advanced technology that replicates the conditions under which diamonds naturally form. Chemically, physically and optically, lab diamonds are identical to mined diamonds — they display the same fire, brilliance and hardness (10 on the Mohs scale). The only difference is their origin. Our lab diamonds are IGI or GIA-certified and graded to the same rigorous 4 C's standards as natural diamonds.
