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.

Each day of Navratri brings a new colour to wear and another reason to dress up. Jewellery can follow the colour of the day or provide a contrast: diamonds lift a bright festive outfit, while coloured gemstones add interest to a simpler one.

For the nine days of celebration, Candere by Kalyan Jewellers brings together diamond and gemstone jewellery that can be styled in more than one way. A pair of earrings worn for a puja can work just as well for an evening of garba; a ring or bracelet can add a finishing touch without asking you to change the rest of your look. The edit offers ideas for pairing jewellery with each day’s colour while choosing pieces you will reach for long after Navratri. Here’s a curated edit-

Day 1 | Orange 

Bring the vibrancy of orange to life with the Dewdrop Delight Diamond and Fancy Gemstone Collar Necklace, featuring colourful gemstones and diamond accents in a statement-making collar silhouette. The matching Dewdrop Delight Diamond and Fancy Gemstone Hoop Earrings carry the same gemstone detailing into an easy-to-wear hoop design, creating a coordinated look that feels festive yet contemporary. Together, the pieces bring colour and sparkle to an orange ensemble while keeping the jewellery look cohesive.

Styling Tip: Pair the set with an orange lehenga, saree or kurta set and keep additional jewellery minimal to let the coordinated necklace and earrings take centre stage.

Day 2 | White

Floral Rush Pearl Diamond Pendant Necklace + Pearl Blossom Essence Diamond Dangle Earrings. For white day, bring together the timeless elegance of pearls and the brilliance of diamonds. The Floral Rush necklace adds a delicate focal point around the neckline, while the Pearl Blossom Essence earrings introduce a graceful drop silhouette. The combination works beautifully for a look that feels festive yet refined.

Styling Tip: Wear the pairing with a white saree, chikankari ensemble or ivory lehenga. Keep the rest of the jewellery understated and let the pearls add softness to the look.

Day 3 | Red

Zona Diamond And Fancy Gemstone Dangle Earrings + Zona Diamond and Fancy Gemstone Collar Necklace. Make a statement in red with the coordinated Zona pairing. The dangle earrings and collar necklace bring together diamonds and colourful gemstones, creating a more expressive look that feels right at home with Navratri dressing. The collar silhouette adds definition around the neckline, while the earrings carry the colour upwards for a balanced finish.

Styling Tip: Style the pair with a classic red saree or lehenga and a clean neckline. Skip a heavy maang tikka or layered necklace so the collar design remains the focal point

Day 4 | Royal Blue

Celestial Peacock Diamond and Gemstone Oval Bracelet + Soft Love Peacock Diamond and Gemstone Dangle Earrings. Royal blue calls for jewellery with an equally regal presence. The Celestial Peacock bracelet combines diamonds and colourful gemstones in an ornate oval silhouette, while the Soft Love Peacock earrings echo the same peacock-inspired detailing. Together, they create a festive pairing that adds colour and character to the look.

Styling Tip: Pair with a royal blue silk saree or lehenga and opt for a sleek bun or pulled-back hairstyle to let the earrings shine.

Day 5 | Yellow

Rosalina Diamond Earrings + Rosalina Diamond Ring. Keep yellow day bright and effortless with the delicate Rosalina pairing. The diamond earrings add a subtle sparkle around the face, while the matching ring brings the same refined touch to the hands. Together, they create an elegant combination that complements the cheerful warmth of yellow without competing with it.

Styling Tip: Pair the duo with a yellow saree, anarkali or contemporary kurta set and add a few slim bangles for a subtle festive finish.

Day 6 | Green

Darshi Diamond And Gemstone Oval Bracelet + Shritika Diamond and Gemstone Pendant Necklace. For green day, bring together floral-inspired detailing and colourful gemstones. The Darshi bracelet adds a delicate touch to the wrist with its floral theme, while the Shritika pendant necklace creates a graceful focal point at the neckline. The combination keeps the look elegant while allowing the colour of the outfit to remain prominent.

Styling Tip: Style the pairing with a deep green saree or lehenga and keep your earrings minimal so the floral and gemstone details remain the focus.

Day 7 | Grey

Anahita Diamond Stud Earrings + Anahita Diamond Ring. Grey brings a more understated mood to the Navratri palette, making it the perfect canvas for diamonds. The Anahita studs offer a clean, refined touch around the face, while the matching ring carries the look through to the hands. Worn together, they create a polished combination that proves festive dressing can be subtle too.

Styling Tip: Pair the set with a silver-grey saree or contemporary grey lehenga and add metallic footwear or a clutch for a modern festive finish.

Day 8 | Purple

Hanshi Diamond And Fancy Gemstone Dangle Earrings + Jasika Diamond and Gemstone Pendant Necklace. Bring a touch of drama to purple day with colourful gemstones and statement silhouettes. The Hanshi dangle earrings add movement and sparkle, while the Jasika pendant necklace creates an elegant focal point around the neckline. Together, they lend a rich, festive finish to the deeper hue of purple.

Styling Tip: Pair the duo with a deep purple saree or lehenga and keep the neckline relatively clean to allow the pendant to stand out.

Day 9 | Peacock Green

Equipoise Diamond and Gemstone Gap Ring + Emeris Diamond Necklace. Close the nine-day celebration with the jewel tones of peacock green. The Equipoise ring brings together diamonds and colourful gemstones in a contemporary open design, while the Emeris diamond necklace adds a refined layer of sparkle around the neckline. The contrast of a modern ring with an elegant necklace makes this pairing feel festive while still being easy to personalise.

Styling Tip: Wear the pair with a peacock green saree or lehenga and add just one or two slim bangles. The mix of colour and diamonds is enough to finish the look.
