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.

Platinum Jewellery Into The Spotlight, PGI’s Retail Partners In India Reporting A 10% Year-On-Year Rise In Retail Sales

Soaring Gold and Silver Prices Reshape Consumer Preferences Amidst Growing Appetite For Contemporary Designs

Published

on

As soaring gold and silver prices reshape consumer preferences, platinum jewellery is emerging as an increasingly attractive alternative in India, driven by affordability concerns, changing aesthetics, and a growing appetite for contemporary designs among younger buyers.

With gold prices touching nearly Rs. 1,58,000 per 10 grams, many consumers—particularly millennials and urban professionals—are rethinking traditional jewellery purchases. Platinum, despite its own sharp rise in prices, is being viewed as a relatively accessible premium option. Currently trading at around Rs. 70,000 per 10 grams, platinum remains significantly cheaper than gold, even after doubling from its 2025 average of Rs. 36,000 per 10 grams.

Jewellers say the shift is especially visible in categories such as wedding bands, daily wear jewellery, and minimalist luxury pieces. Young consumers are increasingly favouring platinum for its understated elegance, durability, and contemporary appeal.

Industry insiders note that platinum has historically struggled for mainstream acceptance in India, where gold dominates both cultural sentiment and investment behaviour. However, sentiment appears to be changing. Retailers said enquiries for platinum have risen sharply as consumers begin to view the metal not only as a style statement but also as a potential store of value.

The renewed interest comes despite higher import duties. India recently increased import duty on gold and silver from 6% to 15%, while platinum duty rose from 6.4% to 15.4%. Yet, the pricing gap between platinum and gold continues to work in platinum’s favour.

Brands are also moving quickly to capitalise on the momentum. Jos Alukkas recently launched a new platinum jewellery campaign featuring actor Dulquer Salmaan as brand ambassador. The campaign positions platinum as a symbol of individuality and sophistication, showcasing rings, chains, bracelets and other designs for men and women.

The trend is also backed by global market data. Platinum Guild International (PGI), in its Q4 2025 report, noted growing momentum for platinum jewellery across India, China, Japan and the US as elevated gold prices alter buying patterns. In India and the Middle East, platinum jewellery outperformed broader market trends, with PGI’s strategic retail partners in India reporting a 10% year-on-year rise in retail sales, aided by festive demand and rising preference for lightweight jewellery.

For India’s jewellery market, platinum’s rise may signal more than a temporary shift driven by gold prices. As consumers increasingly seek jewellery that blends luxury with wearability and individuality, platinum appears to be carving out a stronger, more permanent niche in the country’s evolving precious metals landscape.
