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.

Belgian Consul General H. E. Mr. Pierre Stverlynck Graces BDB Annual Day
- Event marks 42 years of Incorporation and 16 years of Operations
- Recently-appointed Consul-General’s first visit to the Bourse helps strengthen a century-old bond
- Long service awards presented to outstanding employees
Bharat Diamond Bourse today marked 42 years of incorporation and 16 years since the commencement of operations at the BDB Complex in BKC with a special programme graced by H. E. Pierre Stverlynck – Consul General of Belgium in Mumbai as Chief Guest and a number of leading diamantaires.




The function was organised to celebrate the crucial roles played both by the visionaries who conceptualised the need for a centralised infrastructure to boost the diamond trade over four decades ago, and the employees who have run the daily operations in a highly efficient and professional manner.
In his Welcome Address, BDB Vice President, Mehul Shah explained the significance of celebrating twin milestones – 42 years of incorporation and 16 years of operations. He said:

“BDB began with a vision and is now the world’s largest operational bourse, and a symbol of India’s leadership in the diamond world and excellence in every aspect of operations.”
He added, “It is significant that the Consul General of Belgium is with us on this special occasion. Antwerp and Mumbai have a very close relationship, going back more than 100 years. Today the two cities have bonds based on trust, trade and friendship. We are committed to strengthening this bond over the next century as well.”
Congratulating the awardees he said that members may be the owners, but it is the staff who run the complex and have helped build it as the “best of the best” centres for diamonds. “Personal integrity combined with hi-tech surveillance have made BDB one of the safest places in the world,” he explained, and urged all present never to forget that “it is the soldiers who fight and win the wars.” Mr Shah offered compliments to all the awardees and congratulated Team BDB.
Speaking on the occasion, Anoop Mehta, President BDB, welcomed Mr Stverlynck who has recently assumed charge as Consul General of Belgium in Mumbai.

“We are sure that this will be the first of many visits to our Bourse,” he said, noting that the Consulate is the nearest neighbour of the complex.
“The BDB leadership has always enjoyed a very special relationship with the Belgian consulate,” he added, “built on the longstanding bonds between the diamond industry in our two countries.”
Mr Mehta said it was heartening that so many employees had remained loyal to the BDB for multiple years, and urged all gathered to reach out through their department heads to put forward suggestions for further changes and improvements
Mr Stverlynck, who was on his first visit to the Bourse after assuming charge as Consul General, said he was extremely impressed with the facilities available for exporters within the complex. Assuring the trade of cooperation and support, he said he was happy to be personally present to celebrate such a remarkable institution as BDB that has become a key pillar of the India diamond industry.
Congratulating the leadership for its role in steering the bourse, as well as those employees who had received long service awards, Mr. Stverlynck said:

“The consolidated knowledge and experience of so many from those at the top to a number of others who contributed in various ways, is an asset to the industry.”
Special long service awards were presented to employees who completed special milestones during the year. These included 30-year, 25-, 15-, 10- and 5-year service awards to a few employees.
