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.

This Raksha Bandhan, Turn A Timeless Bond Into A Keepsake With Palmonas

Turning A Timeless Tradition Into A Keepsake Of Sibling Love

Published

on

Raksha Bandhan has always been about more than a thread tied around a brother’s wrist. It is a celebration of a bond built over years, from childhood arguments and inside jokes to being each other’s constant through life’s biggest moments. As siblings grow older, the relationship may evolve, but the feeling behind it only becomes stronger.

This Raksha Bandhan, Palmonas brings a contemporary touch to the traditional ritual with its Rakhi collection, designed to celebrate the sibling bond in a way that can be cherished beyond the festival. Palmonas’ Rakhis bring this thought to life by transforming a familiar festive symbol into a keepsake that can be worn and treasured even after Raksha Bandhan. The collection features two distinct options, each offering a different take on the timeless ritual.

The Demi-fine® Rakhi is crafted from Stainless Steel with an 18K gold-tone finish, bringing together contemporary design and meaningful symbolism. The collection features the Harmony Mandala Rakhi, accented with 9 cubic zirconia stones, which symbolizes harmony and balance. Inspired by the mandala, its intricate design reflects the togetherness shared between siblings. The Eternal Tree of Life Rakhi draws inspiration from the symbol of the Tree of Life, representing prosperity, growth and strength. The Guiding Star Rakhi, embellished with 10+ cubic zirconia stones, symbolizes guidance, hope, and protection, reflecting the special bond between siblings and the promise of always being there for one another. Each design is finished with a comfortable knotted thread, bringing together thoughtful symbolism and contemporary craftsmanship.

For those looking for something more timeless, the Silver Rakhi collection is crafted from fine silver, offering a refined take on the traditional Rakhi. The Eternal Infinity BRO Fine Silver Rakhi, designed for brothers, features two white cubic zirconia stones and symbolizes the strength and lifelong bond between siblings. The Eternal Evil Eye Fine Silver Rakhi features the iconic Evil Eye motif, a classic symbol of protection and good fortune, thoughtfully designed to celebrate the unbreakable bond between siblings.

At its heart, Raksha Bandhan is about showing up for each other. The gifts may change with time, but the emotion remains the same. With its Rakhi collection, Palmonas celebrates this evolving expression of sibling love, giving a familiar tradition a modern, wearable form that can become a lasting reminder of the bond between brothers and sisters.

Because some bonds deserve more than a moment, they deserve a keepsake.
