Lab grown diamonds are man-made or artificial diamonds developed using Chemical Vapor Disposition (CVD) or High Pressure High Temperature (HPHT) manufacturing processes, which can be controlled to ensure quality. The product is produced in fine quality in laboratories within a few months, unlike natural diamonds, which require numerous years to be formed. Laboratory grown diamond is increasingly used for various applications, including jewelry, research, cutting tools, and machinery components, which significantly triggers its worldwide sales. Furthermore, they are more cost-effective compared to natural diamonds as it does not need mining and their wider availability further accelerates their adoption across countries.

The COVID-19 crisis negatively influenced the industry's expansion. The novel pandemic led to the temporary closure of laboratories and manufacturing plants, which declined synthetic diamond production. In addition, numerous individuals faced financial strains due to job-related disruptions and business shutdowns, notably in 2020. This factor dropped the demand for non-essential products, including artificial diamonds.
