GJEPC and InCent-LGD, IIT Madras organise Vajra Industry Research and Academic Meet (Vairam 2025)
The Gem & Jewellery Export Promotion Council (GJEPC) and InCent-LGD – IIT Madras, with the support of the Ministry of Commerce & Industry, Government of India, organized “Vajra Industry Research and Academic Meet” (Vairam 2025) on 10th February at IITM Research Park, Chennai. This event was first of its kind in the lab-grown diamond (LGD) sector, bringing together industry thought leaders, researchers, and government officials to explore the potential and future advancements in lab-grown diamonds
India’s Commitment to Lab-Grown Diamond Technology
The meeting underscored India’s commitment to developing indigenously designed CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) systems for lab-grown diamond production.
Support from Key Industry Institutions
VAIRAM 2025 was supported by the Gemological Institute of America (GIA), with the International Gemological Institute (IGI) as the Associate Partner and Economic Law Practice (ELP) as the Co-Partner.
Inaugural Session with Industry Leaders
The inaugural session witnessed the presence of eminent dignitaries, including Prof. V Kamakoti, Director, IIT Madras; Prof. M S Ramachandra Rao, InCent-LGD, IIT Madras; Mr. Manish Jiwani, Co-Convener – LGD Committee, GJEPC; and Mr. Sabyasachi Ray, Executive Director, GJEPC, along with several industry experts.
Government Support for LGD Industry Growth
With a mission to establish India as a global hub for lab-grown diamond technology, the Government of India allocated a grant of Rs. 242.96 crore during the Union Budget 2023 to IIT Madras for research and development over a five-year period. As a result, IIT Madras set up the India Centre for Lab-Grown Diamond (InCent-LGD), a national center aimed at creating state-of-the-art facilities for lab-grown diamond technologies. The center focuses on developing and optimizing diamond growth processes using indigenously designed CVD and HPHT systems, reinforcing India’s position as a leader in lab-grown diamond technology.
Government Perspective on India’s Role in the Diamond Industry
R. Arulanandan, Director, Ministry of Commerce & Industry, Govt. of India said, “India’s strength in the diamond industry is like a diamond itself – resilient, adaptable and ever evolving. With over 50% of the global value chain rooted in India, our focus must now be on data, innovation and policy to drive this sector forward. The future of diamonds – both natural and lab-grown – is India’s to shape.”
GJEPC Chairman’s Address on India’s LGD Future
Vipul Shah, Chairman, GJEPC said, “We would like to extend our sincere gratitude to the Government of India for its continued support to the lab-grown diamond (LGD) industry. With initiatives like the Rs. 242.96 crore grant to IIT Madras and the extension of customs duty exemptions on seeds used in the manufacture of lab-grown diamonds, the government’s vision is clear – India is poised to be a global leader in the LGD sector. GJEPC is proud to partner in this transformative journey and looks forward to driving innovation, export growth, and employment opportunities within this thriving industry.”
Technological Innovation at InCent-LGD, IIT Madras
Prof. M S Ramachandra Rao, InCent-LGD, IIT Madras said, “InCent-LGD is on track to revolutionize the lab-grown diamond industry with the development of indigenous MPCVD and HPHT machines within next 2 years. This innovation will significantly reduce India’s reliance on imports, positioning the country as a global leader in the production of high-quality lab-grown diamonds. Our commitment to advancing technology and fostering industry collaboration will ensure that India not only meets the rising demand but leads the way in diamond innovation.”
Industry Collaboration for Policy and Growth
Manish Jiwani, Co-Convener, LGD Committee, GJEPC, praised the brilliance of IIT Madras and its work through the India Centre for Lab-Grown Diamond (InCent-LGD). He emphasized the need for stronger collaboration between the industry and research institutions, ensuring that advancements align with industry requirements. He also highlighted the importance of conducting a global study to frame policies that would drive growth and productivity in the sector. Noticing that India still imports 70% of the lab-grown diamond rough required for production, he expressed confidence that the technology being developed by IIT Madras will help drive the country towards Aatmanirbharta (self-reliance) in LGD production.”
India’s Advantage in the Lab-Grown Diamond Industry
Sabyasachi Ray, ED, GJEPC said, “India stands at a unique advantage in the lab-grown diamond industry. With the entire value chain—from production to finished jewellery—happening domestically, India is positioned to become the largest producer of rough LGDs and the hub for cutting, polishing, and global trade. This not only strengthens our global position in the gem and jewellery sector but also opens doors to contribute to diverse industrial applications, making India the future epicenter of LGD technology and innovation.”
Presentations on Research and Regulations
Following the inaugural session, Prof. M S Ramachandra Rao provided an in-depth introduction to InCent-LGD, highlighting its objectives and research initiatives. This was followed by a presentation by Mr. Nishant Shah, Partner at Economic Law Practice (ELP), offering insights into the regulatory and commercial landscape of the LGD industry.
Panel Discussions on Key Aspects of the LGD Industry
Panel 1: Beyond Gems – Next-Generation Applications of Lab-Grown Diamonds
Experts highlighted the immense potential of LGDs in sectors like electronics, aerospace, defence, water treatment, and advanced manufacturing, because of their hardness, thermal conductivity, and chemical stability. The discussions underscored applications in high-performance cutting tools, thermal management systems, quantum computing, and precision sensors.
Panel 2: Lab-Grown Diamond Growth and Treatment – Recipes and Challenges (CVD & HPHT Methods)
Experts delved into the intricacies of CVD and HPHT methods, emphasizing the need for optimizing growth parameters, controlling impurities, and enhancing treatment techniques to produce superior-quality diamonds.
Panel 3: Diamond Quality Checks and Certification (Gem, Jewellery, and Seeds)
Experts highlighted the complexities of ensuring accuracy and consistency in grading. The need for industry-wide standardization and advanced testing methodologies was emphasized to detect undisclosed synthetics and ensure reliable certification.
Panel 4: Lab-Grown Diamond Machines and Processing Equipment (CVD, HPHT, Laser Cutting and Polishing, Analytical Instruments)
The panel emphasized the challenges of creating high-precision, cost-effective, and scalable equipment for mass production, underscoring the importance of indigenous manufacturing to reduce dependency on imports.
