Strategic Autonomy in the Lab-Grown Diamond Sector: Policy Roadmap for Global Leadership

India, traditionally known as the global hub for natural diamond cutting and polishing, is now pivoting toward a more technologically advanced frontier: the lab-grown diamond (LGD) ecosystem. Recognizing the immense potential of this sector to generate high-value employment and boost exports, the Union government has unveiled a strategic roadmap to secure end-to-end control over the LGD value chain. This initiative marks a shift from mere processing to comprehensive indigenization, encompassing the manufacturing of specialized machinery, large-scale production, and the development of indigenous global brands. The LGD sector is characterized by its ability to replicate the physical, chemical, and optical properties of natural diamonds through advanced technological processes like Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT). By focusing on the indigenization of machinery, India aims to reduce its reliance on imported technology, thereby lowering production costs and enhancing the competitiveness of domestic manufacturers. This policy push is not merely an industrial strategy but a move toward technological sovereignty in a sector that is increasingly disrupting the traditional luxury jewelry market.
