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.

Lukson Builds India’s Sustainability Benchmark For LGD With A Fully Solar Powered Manufacturing Facility
Lukson Combines A Solar Powered CVD Facility With 500 Reactors, Internationally Certified Stones and A Group Legacy Of Over 1 Lakh Trees Planted Across Gujarat
As India’s lab grown diamond market accelerates, most brands in the category lean on a single claim, that a diamond grown in a lab is kinder to the planet than one pulled out of it. Lukson, the vertically integrated lab grown diamond jewellery brand from the JK Star Group, is going several steps further, backing that claim at the infrastructure level with one of the few fully solar powered diamond growing operations in the country.
At the heart of this story is the Group’s CVD diamond growing facility in Surat, Gujarat, operated under AVP Star, the JK Star Group’s lab grown diamond manufacturing arm. The facility runs entirely on solar power drawn from the Group’s dedicated solar plant in Navsari, Gujarat, and houses 500 CVD reactors, where every Lukson diamond begins its journey as a tiny seed. From growing and coring to slicing, laser processing, cutting, polishing and grading, every stage is handled in house, giving the brand an unbroken chain of quality control and traceability that few players in the category can match.
The commitment extends well beyond the factory. The Group has planted over 1 lakh trees across Gujarat as part of its environmental programme, while its philanthropic arm, the JK Star Charitable Trust, has contributed over 10 percent of net profits from all five group companies since 2019 towards education, healthcare, tree plantation, environmental sustainability and food distribution.
The stones themselves carry independent proof. Lukson’s lab grown diamonds are certified by leading international laboratories including IGI, GIA and GCAL, with an inventory of around 40,000 certified stones held across the Group’s New York and India offices.
Vedant Lukhi, Co-Founder, Lukson Who leads the Group’s CVD diamond growing technology and operations, Said:

“Lab grown does not automatically mean sustainable. A diamond grown in a lab still needs energy, and if that energy comes from fossil fuels, the sustainability story falls apart”
“That is why we invested in making our facility solar powered. When the factory growing your diamond runs on the sun, sustainability stops being a marketing line and becomes something you can walk into, measure and verify. That is the standard we believe the entire industry should be held to.”
Anand Lukhi, CEO and Co-Founder, Lukson Said:
“For us, sustainability was never an afterthought or a trend to ride, it is the inheritance we chose to build on.”

“We come from a family that has spent over three decades in diamonds, and when we imagined Lukson, we were clear that the next generation of Indian consumers deserves jewellery they can feel genuinely good about, in how it looks, how it is priced and how it is made. Our customers should never have to choose between beauty and responsibility. With Lukson, they get both, backed by proof at every step from the reactor to the retail shelf.”
Launched in January 2025 by Anand Lukhi and Vedant Lukhi as the JK Star Group’s first D2C venture, Lukson brings this manufacturing depth directly to the modern Indian consumer, offering certified lab grown diamond jewellery crafted in 9KT, 14KT and 18KT gold, backed by BIS hallmarking and a lifetime buyback policy. The brand retails across ten cities including Mumbai, Delhi, Gurugram, Noida, Pune, Hyderabad, Ahmedabad, Chennai, Jaipur and Guwahati, alongside Amazon, AJIO, Pernia’s Pop Up Shop, Eternz and lukson.co, with try at home and video shopping convenience across key cities.
