Lab Grown Diamonds are chemically identical to natural diamonds. The technical difference is that they’re not billions of years old. Lab-grown diamonds are grown in factories using sophisticated chemical synthesis over a period of 1-4 weeks. Once grown, they are polished with the same tools and brought to market in the same manner as natural diamonds.

Lab-grown diamonds have identical refractive index and optical qualities. Lab-grown diamonds are even graded using the same color and clarity scale as natural diamonds. In casual viewing, they are identical to natural diamonds.
