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.

Quarterly Update: Q1 FY2027- Kalyan Jewellers
Q1 FY2027 highlights robust revenue growth, expanding global footprint, and continued investment in festive season readiness.
The recently concluded quarter has been a very satisfying one, recording consolidated revenue growth of approximately 38% when compared to the same period in the previous financial year.
We saw revenue growth in excess of 38% for our India operations during Q1 FY2027 as compared to Q1 FY2026, led by robust operating momentum on the ground with healthy same-store-sales-growth across all the key markets in the country despite the 28-day Adhik Maas period falling fully in the recently concluded quarter. Adhik Maas is a once in a 3-year phenomenon during which wedding-related demand tends to take a pause in certain parts of the country. The recently concluded quarter recorded same-store-sales-growth of approximately 28%.
We launched our ‘Shine with India’ Gold Recirculation Campaign during the second half of May with the larger objective of increasing the share of recycled gold and thereby reducing dependence on imported gold. The initiative has been well received by customers, helping us increase the share of recycled gold as a percentage of revenue to over 46% during Q1 FY2027. For the month of June, the share of recycled gold as a percentage of revenue was in excess of 55%.
Our international operations recorded revenue growth of approximately 35% for the recently concluded quarter when compared to the same period during the previous financial year. Within the Middle East specifically, we witnessed revenue growth of approximately 30% for Q1 FY2027 as compared to Q1 FY2026, driven predominantly by same-store-sales-growth despite the impact on footfall during April due to the geopolitical tensions in the region.
International markets contributed approximately 14% to our consolidated revenue for the recently concluded quarter.
Our digital-first jewellery platform, Candere, recorded a revenue growth of approximately 112% during the recently concluded quarter as compared to the same period during the last year.
During the recently concluded quarter, we launched 12 Kalyan showrooms and 5 Candere showrooms in India.
The ongoing quarter has started off well and we are upbeat about the new showroom launches, gearing up with fresh collections and campaigns for the upcoming festive and wedding season across the country.
As of June 30, 2026, our total number of showrooms across India and international markets stood at 524:
- Kalyan India – 354
- Kalyan Middle East – 38
- Kalyan USA – 2
- Kalyan UK – 1
- Candere – 129
The metrics and other details provided above are subject to the Limited Review process by our Statutory Auditors. Post approval of the results for the quarter ended June 30, 2026 by the Board of Directors, a detailed information update will follow. Revenue figures provided above refer to revenue from sale of goods (excluding bullion).
