The only difference is their origin: mined diamonds form underground over millions of years, while lab-grown diamonds are created in a controlled laboratory environment over a few weeks or months by replicating nature's process (usually using the CVD or HPHT method).

Lab-grown diamonds are graded using the same internationally accepted standard as mined diamonds: the 4Cs (Cut, Clarity, Color, Carat). Reputable third-party gemological institutes, such as the IGI (International Gemological Institute), certify our stones, providing an unbiased assessment of their quality. LabGems provides these certification reports with your purchase.
