Yes. Lab-grown diamonds are 100% real diamonds — not simulants like cubic zirconia or moissanite. They share the same crystal structure, hardness (10 on the Mohs scale), brilliance, and chemical composition as mined diamonds.
Lab-grown diamonds are indistinguishable from natural diamonds without specialized equipment, and even professional gemologists rely on advanced tools to identify their origin. They are graded using the same standards — the 4Cs: cut, color, clarity, and carat weight — and certified by the same leading gemological institutions, including the Gemological Institute of America (GIA).
