Lab Grown Ruby vs Natural Ruby

Lab-grown rubies and natural rubies are chemically, physically, and optically identical. Both belong to the corundum family and derive their rich red colour from chromium. With the same crystal structure and a hardness of 9 on the Mohs scale, lab-grown and natural rubies offer equal durability, brilliance, and suitability for fine jewellery. When cut and polished, they are indistinguishable to the naked eye—the only difference lies in their origin, not in their beauty or performance.
