VAJRA INDUSTRY RESEARCH AND ACADEMIC MEET (VAIRAM) 2025 organised by GJEPC, IIT Madras inaugurated in Chennai
The Vajra Industry Research and Academic Meet (Vairam) 2025, a joint effort by GJEPC and InCent LGD IIT Madras, was officially introduced at the IITM Research Park in Chennai.
Madras at IITM Research Park, Chennai, was unveiled by 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 among other dignitaries and industry experts.
The workshop features several panel discussions. “Beyond Gems: Next-Generation Applications of OLab-Grown Diamonds” explores LGDs’ potential in various industries beyond jewellery. “Lab-Grown Diamond Growth and Treatment Recipes and Challenges” delves into the intricacies of CVD and HPHT methods. “Diamond Quality Checks and Certification” addresses the crucial need for standardised quality control for gems, jewellery, and seeds. “Lab Grown Diamond Machines and Processing Equipment” will highlight the importance of indigenous equipment manufacturing to bolster India’s self-reliance. The workshop has drawn 150 + participants from the industry.
Key Takeaways
Diamond Quality Checks & Certification:
- Advanced treatments challenge LGD grading and certification accuracy.
- Key challenges: ensuring grading accuracy, standardization, and detecting undisclosed synthetics.
- Emphasis on advanced testing methods, tech-driven grading, and industry consistency.
- Traceability of tested items is a major issue.
- LGDs are both supplementary and complementary to the diamond industry.
- Mimicking natural diamond growth patterns in LGDs remains a challenge.
LGD Growth & Treatment Recipes: Key Takeaways
- Increasing nitrogen in HPHT accelerates growth, benefiting gem-quality diamonds but not other industrial uses.
- Focus on optimizing growth parameters, impurity control, and enhancement for superior diamonds.
- Challenges include consistency, reducing defects, scalability, and reliance on high-purity raw materials.
- Future focus on refining processes, improving sustainability, and enhancing research-industry collaboration.
Diamond Quality Checks & Certification (Continued): Key Takeaways
Strengthening quality assurance frameworks is essential to ensure consumer trust globally.
Grading LGDs differs from natural diamonds, especially in color; secondary reference masters needed.
Labs must assess hue saturation and intensity, not just color for LGDs.
Clarity characteristics differ due to metallic inclusions in LGDs.
Color grading challenges arise in borderline clusters where AI struggles.
LGDs are cut for perfection, unlike natural diamonds, which are cut for weight retention.

June Marked A Strong Rebound In India’s Gem and Jewellery Exports, Surging 26.51% Year-On-Year On Robust Demand Across Key Products and Global Markets
India’s gem and jewellery exports recorded a strong recovery in June 2026, with gross exports rising 26.51% year-on-year to US$ 2.21 billion (Rs. 21,010.78 crore) compared to US$ 1.75 billion (Rs. 15,023.07 crore) in June 2025. The robust monthly performance was driven by healthy demand for gold jewellery, cut and polished diamonds, silver jewellery and platinum jewellery, lab-grown diamonds across key international markets.
For the April–June 2026 period, India’s overall gross gem and jewellery exports remained stable at US$ 6.61 billion (Rs. 62,588.61 crore), registering a marginal 0.04% growth in US Dollar terms and a 10.76% increase in Rupee terms over the corresponding period last year, demonstrating the sector’s resilience amid continued global economic uncertainties and elevated precious metal prices.
Commenting on the export performance, Shri Kirit Bhansali, Chairman, Gem & Jewellery Export Promotion Council (GJEPC), said,

“The strong rebound in June exports reflects the resilience of India’s gem and jewellery sector amid an evolving global trade environment. While exports during the April–June quarter remained broadly stable, the sharp recovery in June is an encouraging sign for the months ahead. Continued demand from key markets, market diversification, and the benefits of recently concluded trade agreements such as the India–UK CETA are expected to further strengthen export growth. GJEPC will continue to work closely with the Government and industry stakeholders to enhance India’s global competitiveness and unlock new export opportunities.”
“The strong rebound in jewellery exports in June 2026 was supported by a significant correction in international gold prices. Gold prices declined by 10.28% month-on-month, falling from US$ 4,723.88 per troy ounce in May 2026 to US$ 4,238.32 per troy ounce in June 2026. The decline in bullion prices lowered raw material costs, enabling Indian exporters to offer more competitive prices in global markets. This improved price competitiveness, coupled with stronger demand in key overseas markets, boosted export volumes and strengthened buyer sentiment. Additionally, the successful participation of Indian exporters in major jewellery exhibitions in Kuwait and Sharjah further supported export orders and contributed to the strong recovery in June exports. However, the problems in availability of gold to exporters continue due to a technical regulatory issue of GST applicability at the import level by the Nominated Agencies notified by RBI. Council is working with the Govt to resolve this issue.”
