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.

QWEEN Partners With Perfect Corp. to Launch Hyper-Realistic AI-Powered Virtual Jewellery Try-On in India

Partnership brings Physically Based Rendering (PBR) technology to QWEEN’s digital ecosystem, enabling consumers to virtually try on rings, earrings and bracelets with exceptional realism across desktop and mobile.

QWEEN, India’s first self-discovery, 100% natural experiential luxury jewellery brand, has partnered with Perfect Corp., a global leader in artificial intelligence (AI) and augmented reality (AR) technology for the beauty, fashion and luxury industries, to introduce an advanced 3D Virtual Try-On experience for consumers in India.

Powered by Physically Based Rendering (PBR) technology, the solution enables customers to virtually try on QWEEN’s rings, earrings and bracelets in real time across both desktop and mobile devices. The immersive experience allows users to see how each jewellery piece sits, moves, reflects light and complements their features, offering a highly realistic way to explore jewellery before making a purchase or visiting a store.

The partnership reflects QWEEN’s commitment to integrating world-class technology that meets the precision and craftsmanship standards expected in the luxury jewellery segment. Perfect Corp., which serves over 800 global brand partners, has developed technology solutions for leading luxury brands including Louis Vuitton, Tom Ford Fashion, and Parisian high jewellery house REZA.

Its PBR-enabled technology accurately renders gold, natural diamonds and gemstones with realistic texture, reflection, movement and proportion. The platform is designed to support up to 2,300 SKUs, enabling consumers to better evaluate the scale, fit and finish of jewellery beyond conventional product images.

Commenting on the collaboration, Amit Kumar, CEO and Co-Founder of QWEEN,

Said the traditional jewellery-buying journey has offered consumers limited opportunities to independently explore products before they are presented across a counter. He noted that QWEEN aims to change this by giving every woman greater information, control and confidence throughout the discovery process.

He added that Perfect Corp.’s experience working with some of the world’s leading luxury and fashion brands provides QWEEN with the confidence that the platform can deliver the realism, precision and sophistication required for the brand’s luxury positioning.

For QWEEN, the collaboration extends beyond introducing a digital feature. The company believes virtual jewellery discovery should offer the same level of accuracy, detail and craftsmanship as the physical retail experience. This is particularly important considering the diversity of its portfolio, where subtle differences in gold colour, gemstone characteristics, diamond brilliance and jewellery proportions significantly influence how a piece appears on the wearer.

Suyash Motarwar, Co-Founder and CTPO of QWEEN,

said the value of Virtual Try-On lies in its ability to accurately represent proportion, movement, colour and material finish. He highlighted that QWEEN’s collection includes seven colours of gold, 100% natural diamonds, and a wide range of 100% natural gemstones, making realistic rendering critical for the luxury buying experience.

He further noted that Perfect Corp.’s PBR-enabled technology provides the visual precision required for luxury jewellery while its self-service authoring capabilities allow the brand to efficiently scale the experience as its assortment continues to expand.

The Virtual Try-On feature will form part of QWEEN’s broader technology-driven discovery ecosystem, which also includes RFID-enabled jewellery, self-service tablets, detailed digital product information, personalised wishlists, and persona-led discovery. The feature is designed to complement the brand’s physical retail experience by allowing consumers to discover jewellery online, save preferred designs, and continue their purchase journey through QWEEN stores and assisted retail touchpoints.

Alice Chang, Founder and CEO of Perfect Corp,

said India’s jewellery market is built on craftsmanship, personal expression and trust, while today’s consumers increasingly expect digital experiences that reflect those values. She added that the collaboration combines hyper-realistic AR try-on with a scalable 3D authoring workflow, enabling QWEEN to showcase the material richness and individuality of each jewellery piece online while supporting the growth of its digital catalogue.

The partnership underscores QWEEN’s strategy of collaborating with globally recognised technology specialists to build a modern, consumer-centric jewellery experience. By combining the emotional appeal and craftsmanship of luxury jewellery with the convenience, personalisation and independence offered by advanced technology, the brand aims to redefine how women discover, experience and purchase fine jewellery.
