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.

GJC lauds GST 2.0, says it is landmark reform that ushers in a new era of trust, transparency, for GJ sector
It reflects the government’s commitment to ease of doing business and provides jewellers with the confidence to focus on growth, innovation, and customer service.
Rajesh Rokde, Chairman -GJC issued a statement on The 57th GST Council recommendation. Which included a series of measures to simplify tax administration, accelerate refunds and reduce compliance costs, with potential benefits for India’s gem and jewellery manufacturers, exporters, wholesalers and retailers.
The statement read:
GST 2.0 is a landmark reform that ushers in a new era of trust, transparency, and efficiency for the gems and jewellery sector. It reflects the government’s commitment to ease of doing business and provides jewellers with the confidence to focus on growth, innovation, and customer service.
These progressive steps will strengthen industry credibility, safeguard livelihoods, and contribute to sustainable development across India. The Council’s recommendations comprehensively address areas that jewellers have long sought reform in — from smoother movement of goods in transit and faster automated refunds that improve cash flow, to fairer notices that reduce litigation and ensure natural justice.
The rationalization of penalties, reduction of the general penalty cap, and recognition of employee insurance ITC reflect a balanced approach that values both compliance and care for our workforce. Most importantly, the withdrawal of arrest powers and the increase in prosecution thresholds will instill greater trust and confidence across the trade.
Together, these measures will reduce disruption, improve working capital, safeguard livelihoods, and create a more supportive business environment. GJC wholeheartedly welcomes GST 2.0 as a forward-looking framework that empowers jewellers, enhances industry credibility, and contributes to sustainable growth for one of India’s most vital sectors
