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.

Senco Gold & Diamonds is hosting an exclusive jewellery exhibition at its Bikaner store from 14th to 31st August 2026, as customers begin preparing for the upcoming festive and wedding season. At the heart of the exhibition is a celebration of jewellery craftsmanship, bringing together traditional Rajasthani jewellery, regional jewellery craftsmanship and the rich karigari heritage of Kolkata that has been an integral part of Senco’s identity.
The showcase brings the breadth and versatility of Senco’s jewellery offering under one roof, highlighting the distinctive jewellery traditions of Rajasthan, with regional pieces such as Baju Bandh, Rakdi Set, Shishful, Nath, Bangdi, Panchlda, Tinlda and Kantha. These traditional creations reflect the ornate detailing, cultural influences and craftsmanship associated with the region, allowing customers to explore Rajasthan’s jewellery heritage alongside Senco’s broader collection of contemporary and traditional designs.
The exhibition also offers an opportunity to explore the wider portfolio, with brands and collections created for different expressions of jewellery and lifestyle. From lightweight gold jewellery and Aham’s contemporary men’s jewellery to couture-led designs, Vivaha’s bridal offerings and Gossip’s silver and fashion jewellery, the portfolio reflects Senco’s focus on giving customers greater choice across occasions, aesthetics and ways of wearing jewellery.
Designed as more than a jewellery showcase, the exhibition brings together live artistry, entertainment, refreshments and interactive customer experiences, creating a festive environment for customers and families.
The celebrations continue on 15th August with Independence Day and Teej celebrations, alongside live Mehendi Art, Nail Art and jewellery photoshoots. On 16th August, customers can enjoy further exhibition activities, including live beauty experiences and jewellery photoshoots.

Speaking on the occasion, Suvankar Sen, MD & CEO, Senco Gold & Diamonds, said:

“India’s jewellery traditions are incredibly diverse, and that diversity is something we have always celebrated at Senco. Rajasthan has its own rich jewellery language and craftsmanship, while our roots in Kolkata have given us a deep connection with karigari and the art of jewellery making.
Bringing these together in Bikaner allows customers to experience that diversity alongside the breadth of what Senco offers today, from gold and diamonds to 9KT, 14KT and 18KT gold, from necklaces and earrings to kadas, bangles, rings and mangtikkas, and from statement jewellery to lightweight traditional pieces designed for ease of wear. Most importantly, we want customers to experience the trust and craftsmanship that Senco has built over generations, while discovering jewellery that feels relevant to their own celebrations and style.”
