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.

Certified natural diamond jewellery from the House of P N Gadgil & Sons now accessible nationwide through a seamless digital experience
PNGS Reva Diamonds, the premium certified natural diamond jewellery brand from the 195‑year‑old House of P N Gadgil & Sons (PNGS), today announced the launch of its official e‑commerce website, going live on September 16, 2026. The new platform extends the brand’s omnichannel footprint, bringing contemporary, hallmarked diamond jewellery to customers across India with the same trust, transparency, and craftsmanship Reva Diamonds is known for in-store.
The website, https://revadiamonds.com/, offers an immersive browsing experience featuring Reva Diamonds’ signature collections including everyday wear, festive pieces, and bridal jewellery, along with detailed product certification, 360° views, and secure, pan‑India delivery.
With the launch of its official website, Reva Diamonds is also introducing exclusive digital launch offers for customers. As part of The Reva Diamonds Digital Reveal, customers can avail themselves of a flat 50% off on making charges on certified natural diamond jewellery, exclusively on the Reva Diamonds website. Additionally, customers who sign up on the website can enjoy Rs. 1,000 off on their first order by using the code GET1000 at checkout.
Commenting on the launch, Amit Modak, CEO & Director, PNGS Reva Diamond Jewellery Limited, said:
“The launch of our official website marks an important step in Reva Diamonds’ journey as we build a contemporary diamond jewellery brand rooted in the enduring values of the P. N. Gadgil & Sons legacy. Today’s customer does not experience a brand through a single channel; discovery may begin online, the consideration may happen across digital and physical touchpoints, and the final experience is built through trust and personal engagement. Our objective is therefore to create a seamless ecosystem where our digital and retail experiences complement each other.
The website is an extension of our brand—not just a destination to view jewellery, but a platform through which customers can discover our collections, understand our craftsmanship and begin their journey with Reva.”
The website launch comes at a significant stage in Reva Diamonds’ growth journey. Established in December 2024, the brand has been developed as a new-age diamond jewellery proposition carrying forward the heritage of P. N. Gadgil & Sons while creating its own identity around modern diamond jewellery. Reva Diamonds has continued to expand its retail footprint, with the brand currently focused on creating a contemporary jewellery experience for today’s consumers.
Amit Modak brings extensive experience across finance, commodity markets, retail and the jewellery industry to his leadership role at PNGS Reva Diamond Jewellery Limited. He has been associated with Reva since its incorporation and also serves as a Director of P. N. Gadgil & Sons Limited.
With the launch of its official website, Reva Diamonds aims to further strengthen its connection with existing and prospective customers, while creating a digital foundation for the brand’s next phase of growth.
Reva Diamonds currently operates 36 locations through a mix of exclusive showrooms and shop‑in‑shop formats, with a strong presence in Maharashtra and ongoing expansion into new markets.
